Mrs. Martin, the science coach, poured 84 ounces of water into a container. The container was then 7/9 full. What was the capacity of the container?

Answer 1

7/9 equals 84
so
find the equality of 1/9 to 84
then add the 1/9 and 1/9 together
and then you have your answer

Answer 2

Sheer Nonsense!

7/9 does not equal 84,
7/9 equals 7/9

Let the capacity of the container be x ounces, then
(7/9)x = 84
x = 84(9/7) = 108 ounces
