A recipe for homemade modeling clay includes 13 1 3 cup of salt for every cup of water. If there are 6 cups of salt, how many gallons of water are needed?

9/320 gallons of water or 0.028125 gallons of water

Step-by-step explanation:

We are told in the question:

13 1/3 cup of salt = 1 cup of water.

6 cups of salt =

Cross Multiply

= 6 × 1/ 13 1/3

= 6 / 13 1/3

= 6 ÷ 40/3

= 6 × 3/40

= 18/40 cup of water.

= 9/20 cup of water.

16 cups of water = 1 gallon

9/20 cup of water =

= 9/20 × 1/16

= 9/20/ 16

= 9/20 ÷ 16

= 9/20 × 1/16

= 9/320 gallons of water or 0.028125 gallons of water

Therefore, 9/320 gallons of water or 0.028125 gallons of water is needed for 6 cups of salt

=
