76.5 / 8.8 = 8.69318182 approximately = 8 61/88.
You can estimate this by taking 8.8 as 9 and 76.5 as about halfway between 72 and 81 ((81+72)/2=76.5). 72/9=8 and 81/9=9
Halfway between 8 and 9 is 8.5 which approximates the answer of 8.69318182.

There are many ways to do this. It could be 9 into 72, giving you 8, 9 into 81, giving you 9, 8 into 72, giving you 9, and 8 into 80, giving you 10. I would go with 9.
