A fraction is a way of expressing a quantity that is divided into a number
of equal sized parts. For example, each part of a cake, split into four equal
parts, is called a quarter (and represented numerically as 1/4), two quarters
is one half (1/2) of the cake, and eight quarters would make two cakes.
Fractions are written in the form 'a/b', where 'a' and 'b' are whole numbers,
and 'b' is not 0. The number 'a' is called the numerator, and the number 'b'
is called the denominator. For example, the following numbers are all fractions
1/2, 3/7, 6/10, 4/99.
