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
