25/2 = 12.5
19 halves as a decimal is 9.5.
Three halves is one and a half, or 1.5 when written as a decimal.
To turn a mixed fraction into a decimal, you need to treat the fraction part as if it were a division. In this case we have 50 halves or 50/2. Dividing this gives 25. This is then added to the whole part (35) to give 60. So 35 and 50 halves as a decimal is 60.
There are 12.5 halves in 25. This is because a half is equal to 0.5, and when you divide 25 by 0.5, you get 50. Thus, 25 contains 50 halves, and if you consider "2 halves" as one whole, then there are 25 whole units in 25.

Two halves = 2*0.5 = 1 (or 1.0, if you must)
