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?

Answer 1

Answer:  

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

$\begin{array}{l}{=\frac{38}{72}=\frac{2 \times 19}{2 \times 36}} \\\\ {=\frac{19}{36}} \\\\ {=19: 36}\end{array}$

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