Answer provided by our tutors

1 3/8 = 11/8

3 2/5 = 17/5

1 3/10 = 13/10

 

Find least common denominator and convert them. Least common denominator is 40 so:

11/8 * 5/5 = 55/40

17/5 * 8/8 = 136/40

13/10 *4/4 = 52/40

 

Add them all up: 55+136+52 = 243

and divide by 40: 243/40  = 6.075 gallons.
