Yes.
45/117 = 5/1345/117 = 5/1345/117 = 5/1345/117 = 5/13
The smallest number that is a multiple of both 72 and 117 is 936.
Assuming you mean 1167/126... It would simplify as 37/42 Yes 117/126 is 29/42 (divide by 3 on top and bottom)

It is: 84/72 = 7/6 simplified
8/9
7/12
7/12
It is: 56/72 = 7/9 by dividing 56 and 72 by their HCF
The GCF is 9.
