25 tenths.
There are five tenths in a half. 5/10 = 1/2
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
There are ten tenths in one whole. Therefore, 10 + 5 = 15 tenths.

Two and a half tenths [0.25]. It depends on tenths of what you are referring to. Agree that there are two and a half tenths of a mile in 0.25 miles, but if you want to know how many tenths of anything else, such as kilometers, the answer is entirely different.
One half is five tenths. One fifth is two tenths. One half less one fifths is five tenths less two tenths, or three tenths. .5 - .2 = .3
You solve this by dividing 1 1/2 by 1/10.
