About fractions

A fraction is the result of a division of two whole numbers. In other words, a fraction describes how many parts of a certain size there are, for example, one-half, five-eighths, three-quarters or seven-ninths. A fraction consists of a numerator and a denominator (the number above the scoreline is called the numerator, the number below the scoreline is the denominator). The numerator represents a number of equal parts and the denominator indicates how many of those parts make up a whole. The denominator can not be zero. If the numerator is smaller than the denominator, the fraction is located between 0 and 1.
