A fraction is a way to represent parts of a whole. The fraction 2/3 represents two of three equal parts. See Figure 1.5. In the fraction 2/3, the 2 is called the numerator and the 3 is called the denominator. The line is called the fraction bar.
A fraction is written ab,ab, where b≠0b≠0 and
a is the numerator and b is the denominator.
A fraction represents parts of a whole. The denominator bb is the number of equal parts the whole has been divided into, and the numerator aa indicates how many parts are included.
