2/3 cannot be simplified further.
3/4
13/100
0.23 = 23/100
8016 is an integer, and there is no sensible way to represent it as a fraction.
As a whole number with a fraction, that's three and six tenths (3 and 6/10ths). This can be expressed at 3.6
72/100 = 18/25
8/40 = 1/5
0.05 = 5/100 = 1/20
No but as a decimal 9/20 is equivalent to 0.45
2/2 = 1
2/27
2 over 4 can be simplified to 1 over 2.
