photoshop1234 [79]

Answer:

114 3/8 gallons

Step-by-step explanation:

To solve the question, we multiply by the number of gallons and the amount travelled per gallon:

Let's convert all fractions to improper fractions:

15 1/4 = (15*4 + 1)/4 = 61/4

7 1/2 = (7*2 + 1)/2 = 15/2

Multiply the numerators and the denominators:

61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8
