Robby has 6 orange juice containers. Each on gallon container is 2/3 full. Sophie says he only needs 4 containers to carry all of it. is she right?

To determine of 4 containers are all that are needed, you will find the total number of gallons that are in the 6 containers by multiplying the 2/3 gallon in each container by 6.

2/3 x 6 gallons = 4 gallons.

You would be able to put all the orange juice in 4 containers.
