Question

Every week, Mr. Kirkson uses 3/16 gallon of water to water every 1/3 square foot of his garden.

How many gallons of water does Mr. Kirkson use per square foot to water his garden each week?

fraction in simplest form.

Answer 1

He uses 3/16 gal for 1/3 square foot.

1/3 square foot is 1/3 of 1 square foot.

1 square foot is 3 times as much area as 1/3 square foot, so he must use 3 times as much water. We need to multiply 3 * 3/16.

3 * 3/16 = 3/1 * 3/16 = 9/16

Answer: He uses 9/16 gallon.
