Question

You use 4 gallons of water on 30 plants in your garden. At that rate, how much water
will it take to water 45 plants?
gallons

Answer 1

6 gallons

If you have 4 gallons for 30 plants, half of 4 gallons is 2, which will water 15 plants. Add 4 gallons plus 2 gallons, it gives you 6 gallons and 45 plants.
