Compare the size of 13 out of 12 and 25 out of 26 and 39 out of 38 And 10 out of 13, 21 out of 36, and 32 out of 39

13/12=1+1/12
26/25=1+1/25
39/38=1+1/38
The size of the above three numbers is obvious. Needless to say
10/13=1-3/13
21/36=1-15/36=1-5/12=1-3/7.2
32/39=1-7/39=1-3.5/13
Observation shows that 32 / 39 > 10 / 13 > 21 / 36
