Ok, so all you have to do is make it an improper fraction. If you do not know how to do that all you have to do is 16 times 5 plus 1 equals 81 over 5. Then you do 5 times 5 equals 25 plus 2 equals 27 over 5. Then you multiply 81 and 25. T hen that would be you numerator. Then you multiply 5 time 5 and that would be your denominator. Then you divide the denominator by the numinator, then yo uhave your answer!
