Final answer:
The container can hold 2 1/4 cups.
Step-by-step explanation:
To find out how many cups fill a container, we need to determine the capacity of the container. In this case, we know that 1 1/2 cups fill 2/3 of the container. To find the capacity of the container, we can set up a proportion as follows:
1 1/2 cups / 2/3 = x cups / 1 container
Next, we can simplify the proportion:
1 1/2 * 3/2 = x
3/2 * 3/2 = x
9/4 = x
So, the container can hold 9/4 cups or 2 1/4 cups.
