A 20-ounce box of noodles contains 10 full servings. You like smaller servings; so you eat 7/8 of a full serving each time. After you eat as many of your size servings as possible, how many ounces of noodles will be left in the box?

Answer 1

full serving = 20 / 10 = 2 oz
7/8 * 2 = 7/4 oz = small serving
20oz /(7/4) = 80/7 = 11 3/7servings
so you ate 11 servings
and you have 3/7 of a serving left over
3/7 * 7/4 oz = 3/4 of an oz

Answer 2

Yes
