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
100 ÷ 15 = 6 2/3 → 6 2/3 × 15 = 100
(2/3) ÷ (4/15) = (2/3) x (15/4) = 30/12 = 5/2 = 2.5
10/15 2/3 = 10/15 10/15 = 3/5
15 + 23 = 38 1/5 + 2/3 = 3/15 + 10/15 = 13/15
3(3+2)=15
It is: 2/3 times 15 which is the same as 2/3 of 15 = 10
15 + 2/3 n = 30n = 3/2 x (30 - 15) = 22.5 or 221/2
8 days. I say 10 days. Day 1, jumps 3 feet, slides back 2 feet equals 1 foot up on Day 1. Day 2, jumps 3 feet, slides back 2 feet equals 1 foot up on Day 2, plus 1 from Day 1 = 2 feet. Day 3, jumps 3 feet, slides back 2 feet equals 1 foot up on Day 3, plus 1 from Day 1 and 1 from Day 2 = 3 feet. etc. until Day 10 when his jumps total ten feet up.
2, 3 and 5 are prime numbers but 15 is a composite number because it has more than two factors
2/3 - 3/5 = 1/15 2/3 = 10/15 3/5 = 9/15 10/15 - 9/15 = 1/15
(x + 3)(x + 3) = (x + 2)(x + 2) + 11 x^2 + 6x + 9 = X^2 + 4x + 15 6x + 9 = 4x + 15 2x + 9 = 15 2x = 6 x = 3 Check it. 3 + 3 squared (36) is 11 more than 3 + 2 squared (25) It checks.
5 + 17 = 22 5 x 3 = 15 15 + 2 = 17
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
2/3 + 2/5 is 1 1/15
