Simplify Fractions Calculator

The Simplify Fractions Calculator lets you reduce fractions to their lowest terms instantly. Just enter one or more fractions like 8/12 or 50/100, and the tool simplifies them showing you the reduced form, the GCD used, and optional step explanations.

This is a fast way to check homework, prep answer keys, or reduce a batch of values at once. Everything happens live, in your browser, with no signup or install.

How to Use:

Type or paste fractions into the Input Fractions box. Use one fraction per line. Example:

8/12
15/35
50/100
9/27

The output updates automatically in the Simplified Output box. You can adjust the format using the toggles:

• Show GCD used – adds the greatest common divisor (e.g., GCD = 4)
• Show steps – appends the divide step used (e.g., “divide both by 4”)

Click Convert to manually update or just type and it will react instantly. Click Copy to grab the result the output will flash to confirm.

What Simplify Fractions Calculator can do:

This tool reduces fractions to their simplest form using GCD-based logic. It works with:

• Common fractions
• Improper fractions
• Equivalent fractions
• Multi-line input

You can paste in a set of fractions, and it will process them all at once. This makes it useful for:

• Students simplifying answers
• Teachers generating clean solution keys
• Anyone converting raw fraction output into simplest form

The tool checks for valid format and ignores invalid lines automatically.

Example:

If you enter the following fractions:

8/12  
15/35  
50/100  
9/27

With both “Show GCD used” and “Show steps” toggled on, the tool will output:

8/12 = 2/3 (GCD = 4) → divide both by 4  
15/35 = 3/7 (GCD = 5) → divide both by 5  
50/100 = 1/2 (GCD = 50) → divide both by 50  
9/27 = 1/3 (GCD = 9) → divide both by 9

If you turn off “Show steps”, the output becomes:

8/12 = 2/3 (GCD = 4)  
15/35 = 3/7 (GCD = 5)  
50/100 = 1/2 (GCD = 50)  
9/27 = 1/3 (GCD = 9)

And with both toggles off, you’ll get a clean list of simplified results:

8/12 = 2/3  
15/35 = 3/7  
50/100 = 1/2  
9/27 = 1/3

This tool is great for reducing fractions quickly while optionally showing the math behind is perfect for learning, teaching, or checking your work.
