Stella bought a 100-pound sack of flour to make bread for the bakery. If 7/8 of a pound of flour is needed for each loaf, how many loaves can she make? What fraction of a pound of flour is left over?

Answer 1

(1 loaf / (7/8) pound )(100 pounds) = 800 /7 loaves
= 114 2/7 loaves
so 114 loaves + 2/7 of a loaf
how many pounds is 2/7 of a loaf?
(2/7) loaf * ( 7/8) pounds/loaf = 2/8 = 1/4 pound left over

Answer 2

100 / (7/8)
100 * (8/7) = 800/7 = 114 loaves

114*(7/8) = 99 3/4 pounds

Answer 3

114 loaves plus 0.285714285714 (left over)
Divide 7/8 = .875
.875 into 100 pounds of flour = 114 loaves with 2/7 or .02857+ left over.
