3 : 27
18 : 25
5 : 8
9 : 20


​

Answer 1

Answer:

$\frac{a}{b} = \frac{5}{8}$

$\frac{b}{c} = \frac{18}{25}$

$\frac{a}{b} \times \frac{b}{c} = \frac{5}{8} \times \frac{18}{25} = \frac{9}{20}$

Answer 2

Answer:

__________________

A/B= 5/8

B/C= 18/25

A/B× B/C= 5/8 × 18/25

A/C = 9/20

A:C= 9:20

Hope it will help you....
