Step-by-step explanation:
Given,
The length of a cell phone(l) = 82 mm and
The width of a cell phone(b) = 36 mm
Find, the ratio of the width to the length of a cell phone = ?
∴ The ratio of the width to the length of a cell phone
= 36 mm : 82 mm
= 36 : 82
Divided by 2, we get
= [tex]\dfrac{36}{2}[/tex] : [tex]\dfrac{82}{2}[/tex]
= 18 : 41
Thus, the ratio of the width to the length of a cell phone is 18 : 41.
