a box of rotini noodles contains 10 servings. If you eat 7/8 of the recommended serving as a meal, how many complete meals can you get from one box

11 whole meals

Step-by-step explanation:

Lets say that you have 800 noodles in one box. The serving size would be 80 noodles / meal. Then the question says you eat 7/8 of the recommended meal, which would be 70 noodles. When you divide 800 by 70, you get 11.4285714286 meals. Remember that the question is asking for full meals, so you round down to 11 full meals.

If you want a more algebraic

10 servings () = 10 (8 / 7) = 80/7 = 11.4285714286 meals.

round down to 11 full meals.
