Answer:
1 and 3/40th gallon
Step-by-step explanation:
1 1/4 = 5/4 = 50/40 yellow paint
1 1/5 = 6/5 = 48/40 green paint
7/8 = 35/40 blue paint
3/4 = 30/40
50/40 - 30/40 = 20/40 yellow paint
48/40 - 30/40 = 18/40 green paint
35/40 - 30/40 = 5/40 blue paint
20/40 + 18/40 + 5/40 = 43/40 = 1 3/40
There are 1 and 3/40ths gallons left after painting the mural.
