Answer 1

(i)Given ratio of $72$ to $60$ is$=\frac{72}{60}$
$=\frac{36}{30}$
$=\frac{18\times 2}{15\times 2}$
$=\frac{6\times 3}{5\times 3}$
$=\frac{6}{5}$

(ii) Ratio of $38$ to $57$ is $\frac{38}{57}$
$=\frac{19\times 2}{19\times 3}$
$=\frac{2}{3}$

(iii) Ratio of $52$ to $78$ is $=\frac{52}{78}$
