please helpp!! Christina wants to paint her garage. She buys 1 1/2 gallons of paint. She uses 2/5 of a gallon of paint for one wall and then she buys 2 more gallons. How many gallons of paint does she have left?

1 1/2 = 1 5/10

2/5 = 4/10

1 5/10 - 4/10 = 1 1/10

1 1/10 + 2 = 3 1/10

3 1/10 gallons of paint left

31/10 gallons of paint.

Step-by-step explanation:

Find common denominators.

3/2 = 15/10

2/5 = 4/10

15/10 - 4/10 = 11/10

2 + 11/10 = 31/10
