Nina is jumping on a trampoline . her forth jump is 6 feet high. each bounce afterwards is two-thirds as high as the bounce before it, how high will her sixth bounce be?

Hi there!

This is a fairly simple one, but you can do this problem a couple ways.

1) Just go in order.

6 · 2/3 · 2/3 = 2 2/3 or 2.67

2) Since you start on the fourth jump, and you need to get to the sixth jump, you will need two sets (if you will) of 2/3. So multiply 2/3 by 2/3 (2/3 · 2/3 = 4/9) and multiply that by 6.

6 · 4/9 = 2 3/3 or 2.67

I hope this helps!
