Question

Leslie has a watering can that holds 3 liters of water. She uses 250 milliliters of water on each of her plants.

How many plants can she water?

Answer 1

Change Litres into Mililitres.
3l*1000mili/1l=3000mili
Divide mili by mili.
3000mili/250mili= 12 plants.

Answer 2

Given that amount of water that can be hold into can = 3 liters.

Amount of water used by one plant = 250 mililiters.

Units are not same for given values so we must make all units equal before carrying out any comparision.

We can convert liters into mililiters using formula

1 liter = 1000 mililiters

so 3 liter = 3*1000 = 3000 mililiters

Now we need to find the number of plants that can be watered by 3 liter of water present in can. To do that we just need to divide total amount of water (3000 mililiters) by water used by 1 plant ( 250 mililiters)

`(3000)/(250)=12`

Hence final answer is 12 plants.
