Answer:
9/320 gallons of water or 0.028125 gallons of water

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
=
