Upper a 10-ounce bag of rice noodles makes 11 servings. at that rate, find how many ounces of noodles are needed for 16 servings, to the nearest ounce

Let z represent the number of ounces of noodles needed for 16 servings. A proportion can be written desribing the relationship between ounces and servings.
  10/11 = z/16
This equation can be solved for z by multiplying by 16.
  16×10/11 = z = 14.5454... ≈ 15

15 ounces of noodles are needed for 16 servings.
