The numerator
The numerator does, but you still have to know the denominatorin order to know the size of the portion.
The part of a fraction above the line is called the numerator. It indicates how many parts of a whole are being counted or considered. For example, in the fraction ( \frac{3}{4} ), the numerator is 3, meaning that 3 parts out of 4 are being referenced.
The numerator is the top line , it tells you how many of the fraction you have (enumerates it, if you like). The bottom is the denominator, it tells you what kind of fraction it is (what denomination it is).
The denominator tells you the total of the pieces in the fraction.

It is the denominator
It tells what fraction of a radioactive sample remains after a certain length of time.
If the fraction has been simplified then there is no such number.
That would be the denominator or bottom number of a fraction. This tells you the overall size of the fraction, while the numerator or top number, indicates how many parts of the fraction are there (i.e. 1/9 means you have one of 9 total parts).
It is the numerator in the non-simplified version of the fraction. When simplified, that information is lost.
How many parts are available out of the total number of parts.
The denominator of a fraction tells how many parts make up a whole, and the numerator tells how many of those parts are being considered.
