3 times the different between 37.5 and 24.5

Answers

Difference means you subtract and 37.5 minus 24.5 is 13. 3 times 13 is also 13*3 and 13*3 is 39, so 3 times the difference between 37.5 and 24.5 is 39.

Final answer:

To solve '3 times the difference between 37.5 and 24.5', you first subtract 24.5 from 37.5 to get 13, then multiply this result by 3, which gives 39.
