And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to t

nikdorinn [45]

Answer:

20.9 ounces of rice noodles are required to make 19 servings.

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

$\dfrac{\text{Weight of rice noodles}}{\text{Serivings}} = \dfrac{11}{10} = 1.1$

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

$\dfrac{\text{Weight of rice noodles}}{19} = 1.1\\\\\Rightarrow \text{Weight of rice noodles} = 1.1\times 19\\\Rightarrow \text{Weight of rice noodles} =20.9\text{ ounces}$

Thus, 20.9 ounces of rice noodles are required to make 19 servings.
