Wellington is hosting a graduation party. he poured some pinneapple juice from the container shown below for his guests. the figure shows how much pinneapple juice was left in the container after wellington poured some out. the amount of pinneaple juice shown is 6/7 of the amount originally in the container. was the container full when wellington began pouring? explain how you know.

Given that 3/4 gal is 6/7 of the amount originally present in the container. If we let x be the original amount in the container, we solve x by the equation,
                                               x(6/7) = 3/4
                                                   x = 7/8 gallon
The original amount in the container is only 7/8 gallon. This means that the container was not originally full given that the volume of the container is 1 gallon.
