Set up a ratio:

4 gallons / 30 plants = X gallons / 45 plants

Cross multiply:

4 * 45 = 30 * x

180 = 30x

Divide both sides by 30:

x = 180 / 30

x = 6

It would take 6 gallons.

Answer:

Step-by-step explanation:

4 gallons=30 plants

then

x gallons=45 plants

by cross multiplication of both the equations

x = (45*4)/30

x=180/30

x=6

Hence 6 gallons are used to water 45 plants
