Question

A rectangular sheet of paper is of length 1.2 m and width 21 cm. Find the ratio of the width of the paper to its length.

Answer 1

Given, Length of rectangular sheet = 1.2 m

= 1.2 × 100 cm = 120 cm [because 1 m = 100 cm ]

Width of rectangular sheet = 21 cm

Thus, the ratio of width of paper to its length $=\frac{21}{120}$
$=\frac{7}{40}$
