What Is the Fraction Calculator?
A fraction calculator handles arithmetic with proper and improper fractions. It simplifies results automatically and shows the steps so you can learn how it is done.
The Formula
a/b + c/d = (ad + bc) / bd. a/b x c/d = ac / bd. Always simplifies to lowest terms.
Example
A woodworking project needs 3/8 inch plus 1/4 inch of material. Enter 3/8 + 1/4 = 3/8 + 2/8 = 5/8 inch. A recipe calling for 2/3 cup doubled becomes 2/3 x 2 = 4/3 = 1 1/3 cups.
Common Uses
Cooking, construction, education, woodworking, math homework.
