A water bottle holds 1 1/2 liters of water. A cup holds 1/10 of water when full. How many cups will it take to fill the water bottle?

Answer 1

It will take 15 cups to fill the water bottle.

1 1/2 liters is equal to 1500 milliliters. Since a cup holds 1/10 of water when full, each cup can hold 150 milliliters.

So, 1500 milliliters / 150 milliliters = 10 cups to fill the water bottle.
