She eats 3/4 of a bag each week, and you are asked to find how much she eats in 6 weeks. You would multiply 3/4 by 6, which gets you 9/2, but that is not simplified. You can put 2 into 9 4 times, and still get a leftover of 1. In that case, your answer will be 4 1/2. The complete answer is: Sheila eats 4 and a half bags of carrots in 6 weeks.
