Question

Brayden is making soup. To make the broth, he combines 2/3 cup of vegetable stock and 2/5 cup of chicken stock. Boiling the broth causes 1/4 cup of the liquid to evaporate. How much broth is left after it is boiled? Explain how you solved.

Answer 1

4/5 cup

Explanation:

Hi.

First, what you would want to do is to find the total amount of the liquid before anything evaporated.

2/5 + 2/3

Find a common denominator

6/15 + 10 / 15 = 16/15

Now you know that 16/15 cups is how much broth there was before anything evaporated. Now you want to find out how much broth there was after 1/4 cup evaporated.

To find this, multiply 16/15 × 1/4

You will get 4/15

Lastly, you want to subtract the amount evaporated from the amount that was already there.

16/15 - 4/15 = 12/15 = 4/5 cup
