(a) $16:24::20:30$

$\frac{16}{24}=\frac{2}{3}.......(1)$

$\frac{20}{30}=\frac{2}{3}.......(2)$

As we can see (1) and (2) are equal So, They are in proportion.

$16:24::20:30$

Hence the statement is True.

(b) $21:6::35:10$

$\frac{21}{6}=\frac{7}{2}.......(1)$

$\frac{35}{10}=\frac{7}{2}.......(2)$

As we can see (1) and (2) are equal So, They are in proportion.i.e

. $21:6::35:10$ .

Hence the statement is True.

(c) $12:18::28:12$

$\frac{12}{18}=\frac{2}{3}.......(1)$

$\frac{28}{12}=\frac{7}{3}.......(2)$

As we can see (1) and (2) are not equal So, They are not in proportion.

Hence the statement is False.

(d) $8:9::24:27$

$\frac{8}{9}=\frac{8}{9}.......(1)$

$\frac{24}{27}=\frac{8}{9}.......(2)$

As we can see (1) and (2) are equal So, They are in proportion.i.e.

$8:9::24:27$

Hence the statement is True.

(e) $5.2:3.9::3:4$

$\frac{5.2}{3.9}=\frac{4}{3}.......(1)$

$\frac{3}{4}=\frac{3}{4}.......(2)$

As we can see (1) and (2) are not equal So, They are not in proportion.

Hence the statement is False.

(f) $0.9:0.36::10:4$

$\frac{0.9}{0.36}=\frac{10}{4}.......(1)$

$\frac{10}{4}=\frac{10}{4}.......(2)$

As we can see (1) and (2) are equal So, They are in proportion.i.e.

$0.9:0.36::10:4$

Hence the statement is True.
