Question

Brian makes a cleaning solution using a ratio of 4cups of water to 1 cup of vinegar. Which equationcould be used to find c, the number of cups ofvinegar that Brian should use with 12 cups of water?

A. 4/12 =c
B. 4/1 =12/c
C 4/1 = c/12
D. 4+1 = 12+c

Answer 1

Option B could be used to find c, the number of cups ofvinegar that Brian should use with 12 cups of water

Explanation:

Brian makes a cleaning solution using a ratio of 4 cups of water to 1 cup of vinegar.

Let c be the number of cups of vinegar that Brian should use with 12 cups of water.

1 cup of vinegar uses cup of water = 4

c cups of vinegar uses cup of water = 4c

We are c, the number of cups ofvinegar that Brian should use with 12 cups of water

So, 4c=12

`4=(12)/(c)`

So, equation =
`(4)/(1)=(12)/(c)`

So, Option B could be used to find c, the number of cups ofvinegar that Brian should use with 12 cups of water
