72/(2^6)=??

im only in 7th grad i dont understand that

Looking at the problem tells you that 72 bounces back to 36 (1/2 of the original 72), the next bounce is 18 (again 1/2), the next bound will be 9, the next etc. Make a table like this.

# height

0 72 meters

1 36 meters

2 18 meters

3 9 meters

4 4.5 meters

5 2.25 meters

6 1.125 meters.

But we can save a little time by simply raising 2

then 72/64 = 1.125

I hope this helps.
