Hi there! In order to divide fractions, keep the first fraction the same, change division into multiplication, and flip the second fraction over. 1/5 * 7/3 is 7/15. D is the only one that has that multiplication problem correct and you can see that just by doing the things needed to divide the fraction. The answer is D.
