I think you mean 15+(3+2), which equals 20.
20 jumps.

Answer #2:
On the other hand, this contributor thinks you mean . . .
start at 15 and jump 2, three times. If you do that, you land at 19.

It is: 2/3 times 15 which is the same as 2/3 of 15 = 10
5 + 17 = 22 5 x 3 = 15 15 + 2 = 17
5
this is how you do it: 1 3/5 = 8/5 2/3 = 2/3 so then you find a lowest common denominator (LCD) which in this case is 15 and you put each fraction with the denominator as 15 and multiply the numerator by the same thing you multiplyed the denominator by so 8/5 = 24/15 2/3 = 10/15 then you subtract 24/15-10/15 = 14/15 which is your answer!!!
(2/3) ÷ (4/15) = (2/3) x (15/4) = 30/12 = 5/2 = 2.5
