Question

The length of a steel tape for measurements of buildings is 10 m and its width is 2.4 cm. What is the ratio of its length to width?

Answer 1

Length of the steel tape = 10 m
= $10\times 100\mathrm{cm}$ = 1000 cm

Breadth of the steel tape = 2.4 cm

Ratio of its length to width = $$\begin{gathered} \frac{1000}{2.4}=\frac{10000}{24}=\frac{1250}{3} \\ =1250:3. \end{gathered}$$
