The answer would be D. To find percentage, you would divide the partial number from the total number. In this case, 13/ 20 because 13 tank tops were sold out of 20. 13/20 is .65. To convert decimals to percentage, multiply by 100 and you would get 65% for the first one. Repeat for the next, 15/25, and you would get 60%. Therefore 65% is the greater percentage.
