A fraction (rational number) consists of two parts, the numerator and the denominator, separated by the fraction bar.
The two parts together give meaning to the number represented:
- the numerator (numer = number) tells us how many equal parts there are;
- the denominator (nom = name) tells us the "name" of the fraction - how many equal parts make up the whole.
The fraction two-fifths represents two equal parts of five needed to make a whole (one).
