Jeremy’s house is 45 feet wide. In a photograph the width of the house was 2.5 inches, and its height was 2 inches. What is the actual height of Jeremy’s house?

Hello!

We can use proportions to solve for the actual height of his house. Remember, we must convert from inches to feet:

1 foot = 12 inches

45 ×12 = 540 inches

Set up a proportion:

Cross multiply:

2.5 · x = 540 · 2

2.5x = 1080

Divide both sides by 2.5:

x = 432 inches

Convert back to feet:

432 / 12 = 36 feet

its 4 because 2 times 2 is 4, if you double the number two you get four

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
