Example 4

medium
Calculate \(\frac{7}{8} \div \frac{3}{4}\).

Solution

  1. 1
    Dividing by a fraction = multiplying by its reciprocal.
  2. 2
    \(\frac{7}{8} \div \frac{3}{4} = \frac{7}{8} \times \frac{4}{3}\).
  3. 3
    \(= \frac{7 \times 4}{8 \times 3} = \frac{28}{24} = \frac{7}{6}\).

Answer

\(\dfrac{7}{6}\)
Flip the divisor and multiply: \(\frac{7}{8} \times \frac{4}{3} = \frac{28}{24} = \frac{7}{6}\).
