Frequently Asked Questions

Find the least common denominator (LCD), convert both fractions to equivalent fractions with the LCD, then add the numerators. Example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.

Multiply numerators together and denominators together, then simplify. Example: 2/3 × 3/4 = 6/12 = 1/2. You can also simplify before multiplying by cross-canceling common factors.

An improper fraction has a numerator larger than its denominator (e.g., 7/4). It equals a value greater than 1. It can be converted to a mixed number: 7/4 = 1¾.
