Fraction Calculator

Purpose: Add, subtract, multiply or divide two fractions and see the answer reduced to its simplest form.

Fraction Calculator

The Fraction Calculator adds, subtracts, multiplies, and divides fractions - including mixed numbers - and shows the simplified result along with the working.

How fraction arithmetic works

To add or subtract fractions you need a common denominator; to multiply you multiply numerators and denominators straight across; to divide you multiply by the reciprocal of the second fraction. This calculator does all of that and then reduces the answer to its lowest terms using the greatest common divisor.

For example, 1/2 + 1/3 becomes 3/6 + 2/6 = 5/6, and 2/3 ÷ 4/9 becomes 2/3 × 9/4 = 18/12 = 3/2. Seeing the steps makes it a useful homework companion, not just an answer key.

Mixed numbers and simplifying

Enter mixed numbers like 1 1/2 and the tool converts them to improper fractions, computes the result, and converts back where helpful. To simplify a single fraction, enter it and the reduced form is shown instantly.

Frequently Asked Questions

Can it handle mixed numbers?

Yes. You can enter mixed numbers such as 2 3/4, and the calculator converts them to improper fractions to compute an exact result.

Does it simplify the answer automatically?

Yes. Every result is reduced to its lowest terms using the greatest common divisor of the numerator and denominator.

Does it show the steps?

It shows the key working, including the common denominator and the simplified result, which helps with checking homework.

What happens if I divide by a fraction equal to zero?

Division by zero is undefined, so the calculator flags it rather than returning a number.
