How it works

About this calculator

Fractions can be tricky — adding, subtracting, multiplying, or dividing them often leads to confusion. Our fraction calculator handles all the math for you. Enter two fractions, choose an operation, and get the simplified result instantly. Whether you are a student checking your homework or an adult needing precise measurements, this tool makes fraction math painless.

The formula, explained simply

We convert the fractions to a common denominator, perform the operation, and simplify the result by dividing the numerator and denominator by their greatest common divisor (GCD). The GCD is found using the Euclidean algorithm. The final result is shown as a decimal and also broken into a whole number and remainder fraction if applicable. For example, 3/2 becomes 1 1/2.

When you would use this

Students check math homework and learn fraction operations. Cooks and bakers scale recipes that use fractions. Carpenters and tradespeople work with fractional measurements. Anyone studying for a math test practices with instant feedback. DIY enthusiasts calculate material quantities in fractional units.

Frequently asked questions

How do I add fractions with different denominators?
Find a common denominator, convert both fractions, add the numerators, and simplify. Our calculator does all the steps instantly.
What does "simplifying" a fraction mean?
Dividing the numerator and denominator by their greatest common factor to get the smallest possible numbers. For example, 4/8 simplifies to 1/2.
What is an improper fraction?
A fraction where the numerator is larger than the denominator, like 7/4. Our calculator shows it as a mixed number (1 3/4) and a decimal (1.75).
How do I divide fractions?
Flip the second fraction upside down (reciprocal) and multiply. 1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2.
Can I use negative fractions?
Yes, negative numerators and denominators are supported. Just enter the negative sign in the numerator.
