What is a Reduce Fraction Calculator?

A reduce fraction calculator is a tool to simplify a given fraction to its lowest terms. By identifying and dividing by the greatest common divisor (GCD) of the numerator and the denominator, the calculator helps reduce the fraction.

 

This calculator makes the simplification much easier and faster, saving time and effort.

How to Use the Reduce Fraction Calculator?

Given below is a step-by-step process on how to use the calculator:

 

Step 1: Enter the fraction: Input the numerator and the denominator into the given fields.

 

Step 2: Click on simplify: Click on the simplify button to reduce the fraction and get the result.

 

Step 3: View the result: The calculator will display the simplified fraction instantly.

How to Reduce Fractions?

In order to reduce fractions, there is a simple process that the calculator uses.

 

The greatest common divisor (GCD) of the numerator and denominator is identified, and both are divided by this number to simplify the fraction.

 

For example, to reduce the fraction 8/12: GCD of 8 and 12 is 4. 8 ÷ 4 = 2 12 ÷ 4 = 3 So, 8/12 reduces to 2/3.

Tips and Tricks for Using the Reduce Fraction Calculator

When we use a reduce fraction calculator, there are a few tips and tricks that we can use to make it a bit easier and avoid silly mistakes: -

 

  • Always ensure the fraction is valid; the denominator should never be zero. 
  • Double-check if the fraction is already in its simplest form. 
  • Use the calculator to verify manual simplifications. 
  • Be aware of common factors like 1, which do not change the fraction.

Common Mistakes and How to Avoid Them When Using the Reduce Fraction Calculator

We may think that when using a calculator, mistakes will not happen. But it is possible for children to make mistakes when using a calculator.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Not identifying the GCD correctly.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Make sure to find the greatest common divisor accurately for precise simplification. For example, mistakenly assuming the GCD of 14 and 21 is 3 instead of 7 will lead to incorrect results.

Mistake 2

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Entering the denominator as zero.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Remember that a fraction with a denominator of zero is undefined. Always ensure the denominator is a non-zero value to avoid errors.

Mistake 3

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrectly simplifying fractions.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Verify the simplification by multiplying the simplified fraction's numerator and denominator and checking if it matches the original fraction.

Mistake 4

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Relying solely on the calculator without understanding.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

While calculators are handy, understanding the process helps in verifying results and catching any potential mistakes.

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Assuming all fractions can be simplified.

Problem 1

How do you reduce the fraction 20/30?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the process: Find the GCD of 20 and 30, which is 10.

 

20 ÷ 10 = 2

 

30 ÷ 10 = 3

 

Therefore, 20/30 reduces to 2/3.

Explanation

By dividing both the numerator and the denominator by their GCD, we get the simplified fraction 2/3.

Problem 2

What is the reduced form of 45/60?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the process: Find the GCD of 45 and 60, which is 15.

 

45 ÷ 15 = 3

 

60 ÷ 15 = 4

 

Therefore, 45/60 reduces to 3/4.

Explanation

The fraction simplifies to 3/4 when both the numerator and the denominator are divided by 15.

Problem 3

Simplify the fraction 18/24.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the process: Find the GCD of 18 and 24, which is 6.

 

18 ÷ 6 = 3

 

24 ÷ 6 = 4

 

Therefore, 18/24 reduces to 3/4.

Explanation

Dividing both terms by their GCD results in the simplified fraction 3/4.

Problem 4

Reduce the fraction 32/48 to its simplest form.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the process: Find the GCD of 32 and 48, which is 16.

 

32 ÷ 16 = 2

 

48 ÷ 16 = 3

 

Therefore, 32/48 reduces to 2/3.

Explanation

By simplifying 32/48 using their GCD, the result is 2/3.

Problem 5

How do you simplify 27/36?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the process: Find the GCD of 27 and 36, which is 9.

 

27 ÷ 9 = 3

 

36 ÷ 9 = 4

 

Therefore, 27/36 reduces to 3/4.

Explanation

Simplifying the fraction using the GCD results in 3/4.
