>>15267405it is a natural number, because the hypotenuse you have drawn is made up of a natural number of pixels, and they can be counted.
i would ask you to show me something that is made up of a non-natural multiple of real life things, but i will not because such a thing does not exist.
Each and everything that seems like it is related to non natural numbers can be divided into a natural number of groups of smaller things. things like fractions and such are not real numbers by themselves but only serve to tell the other person that that thing is divisible in the real world into smaller objects.
quarter of a cake may be a fraction, but it is also representable as a natural number of 1 slice. and cake as 4 slices together.
so as you can see, everything can be put in terms of natural numbers
