Mark wants to paint a mural.He has 1 1/3 gallons of yellow paint and 1 1/4 gallons of green paint and 7/8 gallon of blue paint. Mark plans to use 3/4 gallons of each paint color. How many gallons will he have left after painting the mural?
1 1/3 + 1 1/4 + 7/8 - 3 * 3/4
= 32/24 + 30/24 + 21/24 - 54/24 = 29/24 = 1 5/24
