The number 3/2 has no 1 (one) in it. You can come up with ways to extract the number 1 out of it, but the number 3/2 is just 3/2.
You need to go out of your way to change what I wrote to something like (1+1+1)/(1+1), or whatever other examples you may want to come up with.
3/2 = 1.5 = 1 + 1/2 = 2/2 +1/2
1 (one) is just a tool which helps you get to whatever mathematical bs you want to elaborate on.
This is all schizo shit. In reality, you need to define something as one. Is one apple one apple? Are you counting the gasses dissolved in the apple? Are you including the water content? Is one ripe apple and one dried apple the same?
The problem with physics has always been defining the unit. Planck had a go but it was always going to be fucked because it was based on Big G.
