Answer:
The width of new phone = 5.5 inches
Step-by-step explanation:
Given that:
Length of cell phone = 1.4 inches
Width of cell phone = 4.4 inches
Ratio of length to width = 1.4 : 4.4
Length of new version = 1.75 inches
Width of new version = x
Ratio of length to width = 1.75 : x
As the relation is proportional;
[tex]1.4:4.4 ::1.75:x[/tex]
Product of mean = Product of extreme
4.4 * 1.75 = 1.4x
7.7 = 1.4x
1.4x = 7.7
Dividing both sides by 1.4
[tex]\frac{1.4x}{1.4}=\frac{7.7}{1.4}\\x=5.5\\[/tex]
Hence,
The width of new phone = 5.5 inches
