Vito uses 9 liters of water to water 24 flower pots. He is wondering how many liters of water (w) would it take to water 40 flower pots. He assumes he'll use the same amount of water on each pot. How many liters of water does it take to water 40 flower pots?

Answer 1

Vito uses 9 liters of water to water 24 pots, or 9/24 = 0.375 liters of water per pot.
So it would take 40 * 0.375 = <<40*0.375=15>>15 liters of water to water 40 flower pots. Answer: \boxed{15}.
