Experimenting with symmetry

Question

If I have 9+36=45

and then divided by 36=1.25multiply by 36=45 why’s it go back to the same is there anything i can do with this calculation

Does it show any information due to what I found

Answer 1

45/36 is the same as (5/9)/(4/5), which equals 5/4, or 1.25.

1.25 x 36 is the same as (5/4) x (4 x 9), which equals 45, or 5x9.
