First, you formulate a ratio of Audrey's work time to work done. In this case, 3/5 hour : 2/5 square yards. Expressing and simplifying that into a fraction would yield:

3/5 ÷ 2/5 = 3/5 * 5/2 = 3/2

We use this ratio to determine the sq yards she could paint in an hour:

1 hour * (1/(3/2) = 2/3 square yards

I hope I was able to help you with this question. Have a good day.
