Nellie has a watering can that contains 40 cups of water. she pours 1 quart of water on each plant in her yard. if nellie uses all of the water in the watering can, how many plants does she water?

1/4 of 40 cups

To find out what 1/4 of 40 cups is, you need to multiply 1/4 by 40!

1/4 • 40 = 10 cups

So if watering one plant uses 10 cups of water and she uses all of the 40 cups she had, it then means that she watered 4 plants because 4 times 10 equals 40!

Another easier way to see it is that watering a plant takes 1/4 of her water and so if by the end she used 4/4 of her water, it then means that she watered 4 plants! :)
