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
