Question

Simon uses 6 gallons of water on 20 plants in his garden. At that rate how much water will it take to water 30 plants

Answer 1

9 gallons

Explanation:

You can solve by using a proportion.

6 gallons is to 20 plants as x gallons is to 30 plants.

6/20 = x/30

3/10 = x/30

Cross multiply.

10x = 3 × 30

10x = 90

x = 9

Answer: 9 gallons
