Tank holds 12 gallons and it is 5/8 full, so amount = (5/8) × 12.

Compute: (5/8) × 12 = 60/8 = 15/2 gallons = 7 1/2 gallons = 7.5 gallons.

I do not agree with the student. The numerator 5 means "5 parts" out of 8 equal parts of the tank, not 5 gallons. Each part is 12/8 = 1.5 gallons, so 5 parts = 5 × 1.5 = 7.5 gallons.
