If the container contains 1004.8 oz and its only 60% full, then you have to find 60% of 1004.8. Do this by multiplying 0.6 x 1004.8 and then that gives you 602.88. Now you know your answer is that the container contains 602.88 oz when only 60% full. Please let me know if this helps and if I gave the right answer! :)
