Answer:
The width of the new phone will be of 4.37 inches.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
In this question:
Length was of 2.2 inches, after the modification is of 2.09 inches.
Width was of 4.6 inches, after the modification is x. So
2.2 - 2.09
4.6 - x
Applying cross multiplication:
[tex]2.2x = 2.09*4.6[/tex]
[tex]x = \frac{2.09*4.6}{2.2}[/tex]
[tex]x = 4.37[/tex]
The width of the new phone will be of 4.37 inches.
