Question

Mark wants to paint a mural. He has 1/15 gallons of yellow paint, 1/16 gallons of green paint, and 7/8 gallon of blue paint. Mark plans to use 3/4 gallon of each paint color. How many gallons of paint will he have left after painting the mural?

Answer 1

Mark does not have enough yellow or green paint as both are less than 3/4 gallons. He has enough blue paint and will have 1/8 gallon left after using 3/4 gallon for the mural.

Step-by-step explanation:

To determine the amount of paint Mark will have left after painting his mural, we must subtract the amount of paint he plans to use from the amount he currently has for each color. Since gallons are larger than quarts, we know that there are 4 quarts in a gallon for conversion purposes, but we don't need to convert between gallons and quarts for this problem.

For the yellow paint: 1/15 gallons - 3/4 gallons = Not enough yellow paint. Mark does not have enough yellow paint to begin with since 1/15 is less than 3/4.

For the green paint: 1/16 gallons - 3/4 gallons = Not enough green paint. Similar to the yellow paint, Mark does not have enough green paint as 1/16 is less than 3/4.

For the blue paint: 7/8 gallon - 3/4 gallon = 1/8 gallon left. Here, Mark has enough blue paint, and he will have 1/8 gallon left after using 3/4 gallon.

Therefore, Mark will only have blue paint left after painting the mural, and the amount will be 1/8 gallon.
