By how much is 60% of 80 greater than 3/5 of 15?

Concept: To find a percentage or a fraction of a number, multiply the number by that percentage (as a decimal) or by that fraction; asking how much one computed quantity is "greater than" another asks for their difference (larger value minus smaller value).

Application:

1. 60% of 80 = (60/100) × 80 = 48.

2. 3/5 of 15 = (3/5) × 15 = 9.

3. Difference = 48 − 9 = 39.

Cross-check: 60% and 3/5 are the same proportion (3/5 = 60/100), so applying that identical proportion to 80 and to 15 and subtracting must give the same result; also 39 + 9 = 48, which matches 60% of 80, confirming the working is consistent.

Answer: So 60% of 80 is 39 greater than 3/5 of 15.
