Simplifying them with varied numbers can be difficult, but with the right techniques, you can make it easier. Whether you’re working with fractions and decimals, or an algebraic expression, several methods are available to simplify varied numbers.
In this article, we’ll discuss the best techniques you can use to simplify any kind of varied numbers.
Understanding basic mathematical operations
To understand basic mathematical operations, it is essential to clearly understand the four fundamental arithmetic operations: addition, subtraction, multiplication, and division. Here are some techniques to simplify varied numbers which help in doing basic mathematical operations easily:
Prime Factorization: Prime factorization is a useful technique that breaks down complex numbers into their prime factors. Once in the form of prime factorization, it becomes easier to simplify or multiply numbers.
Order of Operations: In solving a math problem with multiple operations, it is important to follow the order of operations, often remembered as PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Rounding: Rounding is a technique that can help simplify numbers, especially when you cannot find an exact solution. When working with large numbers or complex equations, rounding to the nearest whole number or a specific decimal place is useful.
Using these techniques, one can easily simplify and solve complex problems in mathematics.
Identifying common factors in varied numbers
Identifying common factors is an effective technique to simplify varied numbers quickly and easily.
Here are the steps to follow to simplify varied numbers:
First, find the factors of each number. A factor is a number that divides exactly into another number.
Identify the common factors between the numbers.
Multiply the common factors to find the Greatest Common Factor (GCF).
Divide each number by the GCF.
The resulting numbers are the simplified form of the original numbers.
For example, to simplify the numbers 12 and 30:
The factors of 12 are 1, 2, 3, 4, 6, and 12.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The common factors between 12 and 30 are 1, 2, 3, and 6.
The GCF is 6.
12 ÷ 6 = 2 and 30 ÷ 6 = 5.
Therefore, the simplified form of 12 and 30 is 2 and 5, respectively.
Pro tip: Identifying common factors and simplifying numbers is useful for solving math problems quickly and easily.
Applying the distributive property to simplify equations
The distributive property is useful for simplifying equations, especially those with varied numbers. This property allows you to expand and distribute a number or variable to other numbers or variables within a set of parentheses.
Here’s how to apply the distributive property to simply equations with varied numbers:
Identify the number or variable outside the parentheses.
Multiply the number or variable by each number or variable inside the parentheses.
Simplify the resulting equation by combining like terms.
For example, to simplify the equation 3(4x + 5y), you would distribute the 3 to 4x and 5y to obtain 12x + 15y.
Remember that you can also use this property in reverse to factorize equations.
Understanding and applying the distributive property is a fundamental skill that effortlessly simplifies complex mathematical equations.
Simplifying Fractions
Fractions can be confusing, especially when trying to simplify them. Simplifying fractions can help make calculations easier and make them more readable.
In this article, we will discuss several methods for simplifying fractions and discuss the pros and cons of each.

Finding the Greatest Common Factor (GCF) is important in simplifying fractions with varied numbers. It’s a useful skill to keep in mind when working with fractions, as it makes the process of simplifying fractions a lot easier.
Here are the steps to follow to find the Greatest Common Factor of varied numbers:
1. List the factors of each number.
2. Identify the common factors that each number shares.
3. Determine the greatest common factor (GCF) by selecting the highest common factor from the list.
4. Divide the numerator and denominator of the fraction by the GCF to simplify it.
Using the GCF method, you can simplify fractions with varied numbers easily and accurately. Pro Tip: Practice finding the GCF for various sets of numbers to master this useful skill.
Reducing fraction to its simplest form
Simplifying fractions is reducing fractions to their simplest form with the smallest possible numerator and denominator. Follow these steps to simplify fractions:
Step 1: Find the greatest common factor (GCF) of the numerator and denominator.
Step 2: Divide both the numerator and denominator by their GCF.
Step 3: If the numerator and denominator have common factors, repeat step 1 until no common factors remain.
For example, to simplify the fraction 24/36,
Step 1: Find the GCF of 24 and 36, which is 12.
Step 2: Divide the numerator and denominator by 12 to get 2/3.
Step 3: 2 and 3 have no common factors, so 2/3 is already simplest.
Remember, simplifying fractions makes them easier to work with in math problems and helps to avoid errors.
Converting mixed numbers to improper fractions for easy simplification
Converting mixed numbers to improper fractions is a necessary first step in simplifying fractions. It makes multiplying or dividing fractions and arriving at a reduced form easier.
To convert mixed numbers to improper fractions, follow these steps:
- Multiply the whole number by the denominator of the fraction.
- Add the result to the numerator of the fraction. This is the new numerator.
- Keep the same denominator as the original fraction.
- Simplify the fraction if possible.
For example, to convert the mixed number 2 1/3 to an improper fraction:
- Multiply the whole number 2 by the denominator 3, which equals 6.
- Add the result 6 to the numerator 1, which equals 7.
- Keep the same denominator 3.
- The improper fraction is 7/3.
Now, you can simplify the fraction by dividing the numerator and denominator by their greatest common factor. This ensures that fractions are always in their lowest terms, making them easier to compare and perform operations.
Pro tip: Simplifying fractions is always easier after converting mixed numbers to improper ones.
Simplifying Decimals and Percentages
Simplifying decimals and percentages can be challenging, especially if you don’t know the tricks to do it quickly and efficiently. However, simplifying varied numbers can be useful for various applications, including solving math problems, budgeting and financial analysis.
In this article, we will look at the different techniques and methods you can use to simplify decimals and percentages.
Identifying decimal place values and fractions
Identifying decimal place values and fractions is crucial in simplifying decimals and percentages.
Here’s what you need to know:
Decimal place values: Each digit to the right of the decimal point represents a different decimal place value. The first digit represents tenths, the second represents hundredths, the third represents thousandths, and so on.
Fractions: Fractions can be converted to decimals by dividing the numerator by the denominator. To convert decimals to fractions, identify the decimal place value and use it as the denominator. The numerator is the digit to the right of the decimal point, and the whole number is the numerator. Simplify the fraction if possible.
By understanding decimal place values and fractions, you can easily simplify decimals and percentages.
Pro-tip: Use a calculator or a conversion chart to ensure accuracy when converting decimals to fractions and vice versa.
Converting decimals to fractions or percentages for simplification
Converting decimals to fractions or percentages is an essential skill to simplify varied numbers. Here’s how you can do it:
Decimal to Fraction: To convert decimal to fraction, write the decimal number as a fraction, with the decimal as the numerator, and the place value of the last digit as the denominator. Simplify the fraction by dividing numerator and denominator by their common factors, if any.
For example, 0.75 can be written as 75/100, simplifying to 3/4.
Decimal to Percentage: To convert a decimal to a percentage, multiply the decimal by 100 and add a percent sign (%).
For example, 0.75 can be converted to 75% by multiplying it by 100.
Following these simple steps, you can easily simplify varied numbers and solve complex mathematical problems.
Simplifying percentages by dividing by the common factor of 100
When simplifying percentages, the common factor is 100, making it easy to convert them into decimals or fractions.
To simplify a percentage:
– Divide the percentage by 100 to convert it to a decimal.
– Simplify the decimal as needed.
– Convert the decimal back into a percentage by multiplying by 100.
For instance, suppose you want to simplify 75%. Divide 75 by 100 to get 0.75. So, 75% is the same as 0.75. To simplify 0.75 further, multiply the numerator and denominator by 4 to get 3/4. Thus, 75% is equivalent to 3/4.
Simplifying decimals and percentages allows you to perform mathematical operations easily and compare values effectively.
Pro tip: To divide a number by 100, move the decimal point two places to the left.

Complex number simplification is reducing a complex number to its most basic form. This process involves multiplying the numerator and denominator of the given complex number by its conjugate, which produces a simpler expression for the complex number.
Let’s look into how this simplification works and the various methods of simplification.
Identifying real and imaginary parts of complex numbers
Complex numbers consist of a real part and an imaginary part. The real part is a normal number, and the imaginary part is a multiple of the imaginary unit ‘i’. Here’s how you can identify the real and imaginary parts of a complex number:
Look for the terms not multiplied by i: these are the real parts.
Look for the terms multiplied by i: these are the imaginary parts.
For example, consider the complex number 5 + 3i. The real part is 5, and the imaginary part is 3i.
To simplify complex numbers, combine the real parts and imaginary parts separately. For example, to simplify 5 + 3i + 2 – 4i, combine the real parts (5 + 2) and the imaginary parts (3i – 4i) separately to get 7 – i.
By following these simple steps, you can easily identify and simplify the real and imaginary parts of complex numbers for better understanding.
Understanding conjugate pairs to simplify complex numbers
Conjugate pairs are a crucial concept to understand when simplifying complex numbers. The conjugate of a complex number is formed by changing the sign of the imaginary part. For example, the conjugate of (3+4i) is (3-4i).
When simplifying complex numbers, it’s essential to identify and work with their conjugate pairs. Multiplying a complex number by its conjugate results in a real number. This allows us to eliminate the imaginary part and simplify the expression.
Here’s an example-
Simplify (6 + 5i)/(2 + i)
Multiply the numerator and the denominator by the conjugate of the denominator (2-i)
((6+5i)*(2-i))/((2+i)*(2-i))
= (12 -7i)/(5)
= 12/5 – (7/5)i
By correctly identifying and using conjugate pairs, we can simplify complex numbers and make calculations more accessible.
Pro tip: Remember to change the sign of the imaginary part to form a conjugate pair.
Simplifying complex numbers using mathematical operations, such as addition and division
Simplifying complex numbers may seem daunting, but it can be done using mathematical operations such as addition and division.
Here’s how to simplify varied complex numbers:
Addition: To add complex numbers, simply add the real and imaginary parts together, separately. For example, (4 + 2i) + (3 + 5i) = (4 + 3) + (2 + 5)i = 7 + 7i.
Division: To divide complex numbers, multiply the numerator and denominator by the complex conjugate of the denominator. The complex conjugate is the same as the denominator but has the opposite sign between the terms. For example, (4 + 9i) / (1 – 2i) = ((4 + 9i) * (1 + 2i)) / ((1 – 2i) * (1 + 2i)) = (-14 + 17i) / 5.
These operations may seem complex, but simplifying complex numbers becomes simple with practice.
