Answer:
13 bags
Step-by-step explanation:
1: If he has 6 3/4 lbs to start with, this is 6.75 lbs, as 3/4 = 0.75.
2: He wants the new bags to be 1/2 lb, which is 0.5 lbs.
3: If we divide 6.75 by 0.5, we get the exact number of bags he could have - 13.5.
4: However, the bags must be full, so we have to disregard that extra 0.5 bags, and say he can completely fill 13 bags.
