Question

A 6-ounce bag of rice noodles makes 7 servings, At that rate, find how many ounces of noodles are needed for 16 servings, to the nearest ounce.

Answer 1

Set up a proportion:

x is to 16 AS 6 is to 7

 

x/16 = 6/7

cross multiply

7x = 6(16)

7x = 96

x = 96/7

x = 13 5/7

 

nearest whole ounce is 14 ounces

Answer 2

6/7 = n/16

 

Cross multiply and solve for n for your answer.
