What is a numerator and denominator

In a fraction, the numerator represents the number of parts being considered, while the denominator represents the total number of equal parts the whole is divided into. The numerator is written above the fraction line, while the denominator is written below the fraction line. Together, the numerator and denominator form the fraction. For example, in the fraction 3/5, 3 is the numerator and 5 is the denominator.
