Question

Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used to find the number of cups c of chopped celery in the original recipe. How many cups of chopped celery does the original recipe call for?

Answer 1

Cups of chopped celery in original recipe =
`(3)/(4)\ cups`

Explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

`(2)/(3)c=(1)/(2)`

Multiplying both sides by 3/2

`(3)/(2)*(2)/(3)c=(1)/(2)*(3)/(2)\\\\c= (3)/(4)\\`

Hence,

Cups of chopped celery in original recipe =
`(3)/(4)\ cups`
