Question

Find the ratio of the second quantity to the first.
$2kg,500g$

Answer 1

First, we have to convert the quantities to the same unit.
$1kg=1000g$
⇒ $2kg=2\times 1000g=2000g$
∴ Ratio of the second quantity $\left(500g\right)$ to the first quantity $\left(2000g\right)=\frac{\text{Second quantity}}{\text{First quantity}}$
$=\frac{500}{2000}$

$=\frac{1}{4}$

$=1:4$
