Question

Give four rational numbers equivalent to:
(i) $\frac{- 2}{7}$ (ii) $\frac{5}{- 3}$ (iii) $\frac{4}{9}$

Solution

(i) $\frac{- 2}{7}$

Four rational numbers are

$\frac{- 2 \times 2}{7 \times 2}, \frac{- 2 \times 3}{7 \times 3}, \frac{- 2 \times 4}{7 \times 4}, \frac{- 2 \times 5}{7 \times 5} \frac{- 4}{14}, \frac{- 6}{21}, \frac{- 8}{28}, \frac{- 10}{35}$

(ii) $\frac{5}{- 3}$

Four rational numbers are

$\frac{5 \times 2}{- 3 \times 2}, \frac{5 \times 3}{- 3 \times 3}, \frac{5 \times 4}{- 3 \times 4}, \frac{5 \times 5}{- 3 \times 5} \frac{10}{- 6}, \frac{15}{- 9}, \frac{20}{- 12}, \frac{25}{- 15}$

(iii) $\frac{4}{9}$

Four rational numbers are

$\frac{4 \times 2}{9 \times 2}, \frac{4 \times 3}{9 \times 3}, \frac{4 \times 4}{9 \times 4}, \frac{4 \times 5}{9 \times 5} \frac{8}{18}, \frac{12}{27}, \frac{16}{36}, \frac{20}{45}$
