Started out with 32/32. They ate 18/32, 32-18=14; 14/32. To simplify, 7/16 was left.
First you need to give both fractions a common denominator lets say 40. So N would be 8/40 and Z would be 35/40, so Z collected more than N. All together they collected 43/40 which simplifies to be 1 and 2/40 which would again simplify to 1 and 1/20.
