(i)

$\frac{3}{4 } \div \frac{5}{9}$

$\frac{3}{4} \times \frac{9}{5}$

$\frac{27}{20}$

→ 27 : 20

(ii)

$2 \frac{1}{2} \div 1 \frac{1}{5}$

$\frac{5}{2} \div \frac{6}{5}$

$\frac{5}{2} \times \frac{5}{6}$

$\frac{25}{12}$

→ 25 : 12

(iii)

$1.32 \div 21.6$

$\frac{1.32}{21.6}$

$\frac{132}{2160}$

$\frac{11}{180}$

→ 11 : 180
