Final answer:
The painter used 24 ounces of paint.
Step-by-step explanation:
To find the number of ounces used, you can multiply the fraction of the container used by the total number of ounces in the container. In this case, if the painter used ¾ of the 32 ounce container of paint, you can multiply ¾ by 32 to find how many ounces were used:
¾ × 32 = 24
The painter used 24 ounces of paint.
