The Fraction Calculator is a useful math tool for solving fraction operations quickly. It helps students and everyday users calculate fractions without manual mistakes.
What is a Fraction?
A fraction represents a part of a whole. It has two parts: the numerator and denominator. The numerator is the top number, and the denominator is the bottom number.
Fraction Addition Formula
a/b + c/d = (a × d + c × b) / (b × d)
Fraction Subtraction Formula
a/b − c/d = (a × d − c × b) / (b × d)
Fraction Multiplication Formula
a/b × c/d = (a × c) / (b × d)
Fraction Division Formula
a/b ÷ c/d = (a × d) / (b × c)
