About the Fraction Calculator

A fraction calculator handles addition, subtraction, multiplication, and division of fractions, and automatically simplifies the result to its lowest terms. It also converts between fractions, decimals, and mixed numbers, which saves the manual work of finding common denominators or reducing an answer by hand.

Why This Tool Exists

Fraction math is one of those things that's simple in theory but easy to mess up in practice, especially finding a common denominator or remembering to simplify at the end. This tool exists to handle those steps automatically so the final answer is always in its simplest form.

How to Use It

  1. Step 1. Enter your first fraction (numerator and denominator).
  2. Step 2. Choose the operation — add, subtract, multiply, or divide.
  3. Step 3. Enter your second fraction.
  4. Step 4. Click Calculate to see the result, automatically simplified.

Key Features & Benefits

How It Works

For addition and subtraction, the calculator finds a common denominator before combining the fractions, then simplifies the result by dividing both numerator and denominator by their greatest common divisor. For multiplication, it multiplies numerators and denominators directly; for division, it flips the second fraction and multiplies — the same rules taught in school, just handled instantly and correctly every time.

Frequently Asked Questions

How do you add fractions with different denominators?

Find a common denominator first, convert both fractions to that denominator, then add the numerators — this calculator does that step automatically.

Does this calculator simplify the final answer?

Yes, results are automatically reduced to their simplest form by dividing out the greatest common factor.

Can I use mixed numbers as input?

Yes, you can enter mixed numbers directly and the calculator will convert them to improper fractions before calculating.

How do you divide fractions?

Flip (take the reciprocal of) the second fraction, then multiply it by the first — this calculator applies that rule automatically.

Can this convert a fraction to a decimal?

Yes, results can be shown as a decimal equivalent alongside the simplified fraction form.
