Question

Every week, Mr. Kirkson uses 3 1/6 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?

Answer 1

Mr. Kirkson uses 9.60 gallons of water per square foot to water his garden each week.

Explanation:

This problem can be solved by a simple rule of three.

We have that 1/3 = 0.33 square foot of his garden uses uses 3 1/6 = 19/6 = 3.167 gallons of water. How many are used per square foot? So:

1 foot - x gallons

0.33 foot - 3.167 gallons

`0.33x = 3.167`

`x = (3.167)/(0.33)`

`x = 9.60`

Mr. Kirkson uses 9.60 gallons of water per square foot to water his garden each week.

Answer 2

3 1/6 / 1/3 =

19/6 / 1/3 =

19/6 * 3/1 = 57/6 = 9 1/2 gallons per square foot
