A fraction represents a part of a whole number. It consists of a numerator (the top number) and a denominator (the bottom number), separated by a fraction bar. For example, 3/4 means 3 parts out of 4 equal parts. Fractions are used extensively in mathematics, cooking, measurements, and everyday calculations.
Our fraction calculator supports all basic fraction operations including addition, subtraction, multiplication, division, simplification, and conversion between fractions, mixed numbers, and decimals.
To add fractions, find a common denominator, convert both fractions, then add the numerators:
where LCM is the Least Common Multiple of the denominators
To multiply fractions, multiply the numerators together and the denominators together:
where the result should be simplified to lowest terms
