Question
Find the compound ration of $2a: 3b$, $mn: x^2$ and $x: n$
✓
Answer
Required compound ratio $=2 a \times mn \times x : 3 b \times x^2 \times n ^`$
$=\frac{2 a \times m n \times x}{3 b \times x^2 \times n}$
$=\frac{2 a m}{3 b x}=2 a m: 3 b x$
$=\frac{2 a \times m n \times x}{3 b \times x^2 \times n}$
$=\frac{2 a m}{3 b x}=2 a m: 3 b x$
