Question

Find the ratio between

(iii) 60 cm and 2.4 m.

Answer 1

Calculation of the ratio:

The units of the numbers in a ratio is always same.

1 meter is equivalent to 100 cm. So, 2.4 m is equivalent to $2.4\times 100=240$ cm.

Therefore,

$$\begin{gathered} \mathrm{Ratio}\mathrm{of}60\mathrm{cm}\mathrm{and}2.4\mathrm{m}=\frac{60}{240} \\ =\frac{1}{4}(\mathrm{Cancelling}\mathrm{out}\mathrm{the}\mathrm{common}\mathrm{factors}) \end{gathered}$$

Final Answer: The ratio is $1:4$.
