Question 3 (iii)

Give four rational numbers equivalent to:
$\frac{4}{9}$

Answer 1

$\frac{4}{9}\frac{4\times 2}{9\times 2}=\frac{8}{18},\frac{4\times 3}{9\times 3}=\frac{12}{27},\frac{4\times 4}{9\times 4}=\frac{16}{36},\frac{4\times 5}{9\times 5}=\frac{20}{45}$
Therefore, four equivalent rational numbers are $\frac{8}{18},\frac{12}{27},\frac{16}{36},\frac{20}{45}$
