Fraction Operations

This calculator can add, subtract, multiply, and divide two fractions. Answers are simplified automatically.

For addition and subtraction, use a common denominator:

a/b + c/d = (ad + bc) / bd
a/b - c/d = (ad - bc) / bd

For multiplication:

a/b x c/d = ac / bd

For division:

a/b / c/d = a/b x d/c

Simplifying makes the answer easier to read. For example, 6/8 and 3/4 are equal, but 3/4 is simpler.

No. A fraction with zero as the denominator is undefined.
