Mr. Ross is painting a wall that has an area of 142.5 square feet. He uses 3/4 gallon of paint to paint 1/5 of the wall. How many gallons of paint will he need to paint the entire wall? pl dont play around dont answer if its just 4 points

Mr. Ross will need 3 3/4 gallons of paint to paint the entire wall.

Step-by-step explanation:

First, multiply 142.5 by 1/5, which equals 28.5. Now you know how many square feet he painted with 3/4 of the gallon. Divide 28.5 by 3/4, or multiply 28.5 by 4/3. This equals 38, so each gallon will paint 38 square feet. Divide 142.5 by 38, and you will get 3.75. Not sure if you need to change it to a fraction or not, but if you do, it's 3 3/4.

1/5^2 = 7.56/45
