I guess you mean: 17/15 ------ 13/15 which is the same as: 17/15 ÷ 13/15 First: convert the mixed number to an improper fraction, then change the divide to multiply and invert the second fraction; do the multiplication and convert any improper fraction to a mixed number: 17/15 ÷ 13/15 = 22/15 ÷ 13/15 = 22/15 x 15/13 = 22/13 = 19/13
32/13 = 71/13
