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?

Answer

Explanation:

Step1: Find the unit - rate

First, find out how much water is used per plant. The amount of water per plant is $\frac{4}{30}=\frac{2}{15}$ gallons per plant.

Step2: Calculate water for 45 plants

Multiply the unit - rate by the number of plants. So, the amount of water for 45 plants is $\frac{2}{15}\times45$. $\frac{2}{15}\times45 = 2\times3=6$ gallons.

Answer:

6 gallons
