About this Fraction Calculator
The Fraction Calculator adds, subtracts, multiplies, and divides fractions and shows the simplified answer, mixed number, and decimal, with step-by-step work that matches how fractions are taught in school.
Formula
a/b + c/d = (ad + bc)/bd. a/b × c/d = ac/bd. a/b ÷ c/d = ad/bc. Simplify by dividing top and bottom by their greatest common factor.
What you'll need
- • First fraction (numerator and denominator)
- • Operation: +, −, ×, or ÷
- • Second fraction (numerator and denominator)
How it works
- 1. Choose the operation you need.
- 2. For + and −, rewrite both fractions with a common denominator.
- 3. For ×, multiply numerators and denominators.
- 4. For ÷, flip the second fraction and multiply.
- 5. Simplify using the greatest common factor and convert to a mixed number if needed.
Worked example
1/2 + 1/3: common denominator 2 × 3 = 6, so 3/6 + 2/6 = 5/6. For 3/4 ÷ 1/2, flip the second fraction and multiply: 3/4 × 2/1 = 6/4 = 3/2 = 1 1/2.
