pi is a transcendental number, which is a kind of irrational number. As a result it cannot have a fractional form. A convenient approximate fraction is 22/7 so that pi/2 would be approx 11/7 (which is about 0.04% too large).
Any number can be put in fraction form
Pi is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate pi; no common fraction (ratio of whole numbers) can be its exact value).
mm is not a number and so, in itself, it cannot have a fraction form.
358 is in its simplest form, but it is a whole number and not a fraction.

4.75 as a mixed number with a fraction in simplest form = 43/4
A rational number
' 18 ' is not in fraction form. It looks like the job is done.
130 is a whole number and not a fraction. It is already in simplest form.
The fraction in simplest form of 3.25 is 13/4
7.5 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. As a mixed number, it is 7 1/2.
