Answer:
1. 4 ounces of pasta per serving.
2. 20 ounces for 5 servings.
Step-by-step explanation:
3 ounces of pasta makes 3/4 servings of pasta.
We want to get find out how many ounces of pasta needed to make 1 serving of pasta, in other words 4/4 servings of pasta.
To get 3/4 to 4/4, we need to times it by 4/3, since 3/4 * 4/3 = 12/12 = 4/4 = 1.
So to get the ounces of pasta, we need to times 3 by 4/3.
3 * 4/3 = 3/1 * 4/3 = 12/3 = 4 ounces.
There we see that there are 4 ounces of pasta in a serving.
Now that we know that there are 4 ounces of pasta in a serving, we simply multiply to get the amount of ounces of pasta in 5 servings.
We can say that the amount of pasta is directly proportional to the amount of servings.
Direct proportion is the relationship between two variables when their ratio is equal to a constant value.
If there are 4 ounces of pasta in a serving, the amount of servings is multiplied by 5, and since the amount of pasta is directly proportional to the amount of servings, we multiply the ounces of pasta by 5.
4 * 5 = 20.
Here we see that there are 20 ounces of pasta in 5 servings.
Hope this helps.
