Fractions can be tricky — but they don't have to be. Whether you're studying for a math test or need to divide a recipe, our fraction calculator makes it simple.
How to Add Fractions
Same denominator: Add the numerators and keep the denominator
1/5 + 2/5 = 3/5
Different denominators: Find the least common denominator (LCD)
1/3 + 1/4 = 4/12 + 3/12 = 7/12
How to Subtract Fractions
3/4 − 1/6 = 9/12 − 2/12 = 7/12
Find the LCD (12), convert each fraction, then subtract.
How to Multiply Fractions
Simply multiply the numerators and denominators:
2/3 × 3/4 = (2×3) / (3×4) = 6/12 = 1/2
How to Divide Fractions
Flip the second fraction and multiply:
1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2
