It is: 72/66 = 12/11
12/13
72/42 = 12/7
It is: 12/72 = 1/6 simplified
72/132 factor out 12 12*6/12*11 now, as 12 is a shared factor it can be canceled, top and bottom 6/11 --------simplified
47/72 is already simplified
It is: 72/96 = 3/4 simplified
-13/72 cannot be simplified.
Simplified - it's 1/2
55/72
If you divide 42 by 6, you get 7. If you divide 72 by 6, you get 12. 7 over 12 cannot be simplified any further so your answer is 7/12
42/72 factor out a 6 6*7/6*12 eliminate the 6; top and bottom = 7/12 ------------ simplified
