Question

HELP ME PLEASE AND ONLY RIGHT ANSWERS!

The length of a cell phone is 1.4 inches and the width is 3.4 inches. The company making the cell phone wants to make a new version whose length will be 1.54 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?

Answer 1

Answer: 3.74 inches.

Step-by-step explanation: We can use the following to help us solve this proportion:

1.4 / 1.54 = 3.4 / x (where x is the unknown value that we are trying to solve)

1.54 / 1.4 = 1.1

x / 3.4 = 1.1

The only number that can make the following above true is 3.74, so that is your answer.

Let me know if this is right! :)
