Working with Fractions Explained

Fractions represent parts of a whole, made up of a numerator (top number) and a denominator (bottom number).

Basic Fraction Operations:

  • Adding & Subtracting: Requires finding the Least Common Denominator (LCD) before combining the numerators.
  • Multiplying: Multiply straight across (numerator by numerator, denominator by denominator) without finding common denominators.
  • Dividing: Multiply by the reciprocal (flip the second fraction and multiply).

Frequently Asked Questions

How do I add 3/4 + 2/5 step by step?

Find the common denominator 20, convert to 15/20 + 8/20, then add the numerators to get 23/20, which is 1 3/20. The calculator above shows each step.

How do you divide fractions?

Multiply by the reciprocal: flip the second fraction and multiply. For example, 2/3 ÷ 4/5 becomes 2/3 × 5/4 = 10/12 = 5/6.

Does it simplify fractions to lowest terms?

Yes — every result is automatically reduced to lowest terms, and the calculator shows the simplification steps.
