11
To find this, follow these steps:
First, convert 8 and 1/2 into a mixed fraction. Multiply the denominator by the whole number and then add it to the numerator. This should give you 17/2.
Now, you need common denominators, so multiply both the numerator and denominator by 2 to get you 34/4.
Now, divide the numerator (34) by 3 to get the answer of 11.
Hope this helps!
