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?

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

To find the capacity of the container, we need to determine how much water is in each fraction of the container.

Given that the container is 7/9 full, we can set up the following equation:

(7/9) * Capacity = 84 ounces

To isolate the capacity, we can divide both sides of the equation by 7/9:

Capacity = 84 ounces / (7/9)

To divide by a fraction, we can multiply by its reciprocal:

Capacity = 84 ounces * (9/7)

Now, we simplify the expression:

Capacity = 12 * 9 ounces

Capacity = 108 ounces

Therefore, the capacity of the container is 108 ounces.

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
