During dance practice, sasha drank 21⁄2 pints of water, and on the way home she drank 1⁄2 cup of water. how much water did she drink in total? cups and ounces

First, to find how many pints she drank, you divide 21 by 2, which is 10.5. To make things easier, let's convert her cups into decimal form by dividing 1 by 2, leaving us with .5.
Now, let's convert her pints to cups. 10.5 pints is equal to 21 cups. Now, add the cups she drank on the way home.
In total, Sasha drank 21.5 cups of water, or 172 fluid ounces :)

I’m not sure i’m sorry
