HOW TO CANCEL IN ORDER TO SIMPLIFY Or you could cancel to make it easier. 2 3 X 3 8 = the 3 on top and the 3 on bottom are both divisible by 3 and cancel to become 1. The 2 and the 8 have a common factor of 2 and are both divisible by 2. so they cancel and the 2 becomes 1 and the 8 becomes 4. 1 1 X 1 4 = 1 4
