#52# bags

Explanation:

There are 6 acres. He needs #8 2/3# for each acre.

WE could say: #8 2/3 +8 2/3+ 8 2/3 +8 2/3+8 2/3+8 2/3#

and then just ad them all together.

However, multiplication is the short cut for repeated addition.

So it is quicker and easier to do

# 6 xx 8 2/3#

=#cancel6^2 xx26/cancel3#

=#52# bags
