Question

To the nearest milimeter, a cell phone is 72mm long and 38 mm wide. what is the ratio of the width to the length?

(Type the ratio as a simplified fraction)

Answer 1

Ratio of width to length in simplified fraction is 19:36

Solution:

To the nearest milimeter, a cell phone is 72mm long and 38 mm wide

We need to find the ratio of width to length

Given that:

Length of the cell phone is 72 mm

Width of the cell phone is 38 mm

The ratio of width to length can be written as:

width : length = 38 : 72

`\begin{array}{l}{=(38)/(72)=(2 * 19)/(2 * 36)} \\\\ {=(19)/(36)} \\\\ {=19: 36}\end{array}`

Hence ratio of width to length in simplified fraction is 19:36
