There are fifteen tenths in 1 and a half. To convert 1 and a half to tenths, you multiply the whole number (1) by 10 to get 10 tenths, then add the remaining half (0.5) to get a total of 15 tenths. This is because each whole number is equivalent to 10 tenths, and the half represents an additional 5 tenths.
There are ten tenths in one whole. Therefore, 10 + 5 = 15 tenths.
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

Ten tenths equal 1. So to find half of that, devide both sides by 2; you end up with 5 tenths equal one half.
You solve this by dividing 1 1/2 by 1/10.
1/2 = 5/10
If you assume that number 1 equals 10, then there are ten tenths in this. If you take the number up to 3.5, then this would be 35 tenths. However, if you are asking how many tenths are there in 3 and a half from the NUMBER 10, then this works out at 2.85.
Fifteen 1 and a half = 3/2 3/2 x 5/5 = 15/10
25 tenths
