Hope made 7 loaves of bread for the Festival. She needs 50 slices. How many slices would she need to cut from each loaf of bread if she cuts the same number of slices from each loaf?

solution 

50 slices divided by 7 loaves (50/7) equals 7 slices per loaf, with a remainder of 1.  So if Hope cuts seven slices from each loaf, she will have (7 loaves)*(7 slices per loaf) = 49 slices, which is one short of what she needs. 

To get exactly 50 slices, Hope would need to cut 7 slices from 6 loaves (7*6=42 slices) and 8 slices from the last loaf to get 50 exactly (42+8 = 50).

If she cuts the same number of slices from each loaf, she will need to cut 8 slices per loaf, yielding 8*7 = 56 slices, so she gets 6 more slices than she needs.
