1/2 + 3/4
what is 5/6 minus 1/3
divide 7/8 by 1/4

This tool performs the four basic fraction operations for two fractions: addition, subtraction, multiplication, and division. It reduces the final answer automatically, keeps denominators normalized, and gives you one exact fraction result instead of only a decimal estimate.

A fraction calculator is useful when you need to add fractions with unlike denominators, subtract one fraction from another, multiply fractions in worksheet problems, or divide fractions in measurement and recipe math. It also helps when you want to check homework quickly without reworking every arithmetic step.

The exact fraction result keeps the arithmetic precise, which matters for math class, ratio work, and reduced forms. The decimal approximation is useful when you want a quick sense of size, but the simplified fraction is usually the better final answer when exact values matter.

Does this fraction calculator simplify the result?

Yes. The calculator reduces the final answer automatically and also normalizes input fractions so equivalent forms are treated consistently.

Can I use negative fractions?

Yes. The calculator accepts negative numerators or denominators and normalizes the sign so the displayed denominator stays positive.

Can a denominator be 0?

No. A denominator of 0 is invalid, and the calculator will return a validation message instead of a fraction result.
