Question

The length of a cell phone is

Answer 1

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;

$1.4:4.4 ::1.75:x$

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

$\frac{1.4x}{1.4}=\frac{7.7}{1.4}\\x=5.5$

Hence,

The width of new phone = 5.5 inches
