Step-by-step explanation:
The ratio of width to length in simplest form is 19 : 44
<em><u>Solution:</u></em>
Given that, A cell phone is 132 mm long and 57 mm wide
Length of cell phone = 132 mm
Width of cell phone = 57 mm
We have to find the ratio of width and length in simplest form
In ratio form, we know that,
Writing in ratio form, we get
Width : length = 19 : 44
Thus the ratio of width to length in simplest form is 19 : 44
