Answer 1

Answer:

1. 7 jumps.

2. 5 jumps.

Step-by-step explanation:

1 - the frog moves three down to step 4, and two up to step 2. There are      seven steps from 2 to 9, so 7 jumps.

2 - 5 up 3 down means two up, so 9 is four jumps of two along with an additional jump to cover the first step. Hence, 5 jumps.
