Question

Find the compound ratio of:

$\left(i\right)$ $2:3,9:14\text{and}14:27$

Answer 1

Step: Find the compound ratio

Compound ratio $=\frac{\text{product of all}{1}^{st}\text{numbers in ratio}}{\text{product of all}{2}^{nd}\text{numbers in ratio}}$

Compound ratio $=\frac{2\times 9\times 14}{3\times 14\times 27}$

$=\frac{2}{3\times 3}$

$=\frac{2}{9}$

Hence the compound ratio is $2:9$
