Question

Find the ratio of the first quantity to the second.

(2) 20 : 60

Answer 1

We have to convert the quantities to the same unit.
Re 1 = 100 paise
∴ Ratio of the first quantity (90 paise) to the second quantity (100 paise)$=\frac{\mathrm{First}\mathrm{quantity}}{\mathrm{Second}\mathrm{quantity}}$
$$\begin{gathered} =\frac{90}{100} \\ =9:10 \end{gathered}$$
