What is the Fraction Calculator?
A fraction calculator handles arithmetic between fractions — finding a common denominator where needed and simplifying the answer to its lowest terms.
How to Calculate
For adding or subtracting, the fractions are put over a common denominator; for multiplying, numerators and denominators multiply directly; for dividing, you multiply by the reciprocal. The result is then simplified using the greatest common divisor.
Formula
a/b + c/d = (ad + bc) / bd, then simplify
