25 tenths.
There are five tenths in a half. 5/10 = 1/2
Ten tenths equal 1. So to find half of that, devide both sides by 2; you end up with 5 tenths equal one half.
7 1/2 = 7 + 1/2 = 7 + 0.5 = 7.5 (5 tenths) * * * * * I suspect that the question was about how many tenths in the whole of seven and a half. That is, 7.5/(1/10). And the answer to that , is 75
Fifteen 1 and a half = 3/2 3/2 x 5/5 = 15/10

A fifth is 2 tenths, which is 5 tenths (or one half) less than 7 tenths: 7/10-1/5=7/10-2/10=5/10=1/2
There are ten tenths in one whole. Therefore, 10 + 5 = 15 tenths.
75 one-tenths
five 5/10 = 1/2
There are two and a half tenths in .25
