Robin donated bags of grain that each weighed 403 pounds to the local food shelf. If the total weight of the grain was 160 pound
Alexxx [7]
Well.. 160 x 3 = 480. So he would've had to give only 2 bags. But he would've given a fraction of a bag, but if you're only talking whole numbers, then the answer is 2. If you're talking fractions, then the answer is 2.51875.
