Find the compound ratio of:

$(i i)$ $2 a : 3 b, m n : x^{2} and x : n$

Open in App

Solution

Step: Find the compound ratio

Compound ratio $= \frac{product of all 1^{s t} numbers in ratio}{product of all 2^{n d} numbers in ratio}$

Compound ratio $= \frac{2 a \times m n \times x}{3 b \times x^{2} \times n}$

$= \frac{2 a m}{3 b x}$

Hence, the compound ratio is $2 a m : 3 b x$
