Formula
a/b + c/d = (a·d + c·b) / (b·d)\na/b − c/d = (a·d − c·b) / (b·d)\na/b × c/d = (a·c) / (b·d)\na/b ÷ c/d = (a·d) / (b·c)\nThen divide numerator & denominator by their GCD.
FAQ
How do you add two fractions?
Find a common denominator, then add the numerators and simplify. For example, 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
What does "simplified" mean?
It means the fraction is reduced to lowest terms so the numerator and denominator share no common factor.
How do you divide fractions?
Multiply the first fraction by the reciprocal of the second. For example, 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2.
