They both can be divided by nine:
27 / 9 = 3
-------------
180 / 9 = 20
So it's 3 over 20.
No, it can be simplified further.
It is: 104/180 = 26/45
180/360 = 1/2
It is 2/27, which cannot be simplified.
8/27 cannot be simplified further.
11/27 cannot be simplified further.
65%.
It is already simplified.
It is: 3/5 simplified
3/8
It is: 9/5
27/98
