3. Ramona drank 1 5/8 liters of water during soccer practice. She drank 1 1/4 liters of water on the ride home. Which expression could be used to
determine the amount of water, in liters, Ramona drank altogether?

The expression x = could be used to determine the amount of water drank altogether.

Step-by-step explanation:

x = Water drank during practice + Water drank on the ride home

x =

Hence,

The expression x = could be used to determine the amount of water drank altogether.
