If you divide numerator and denominator (top and bottom) by 3, you get 3/4, which is an equivalent fraction.
If the numerator is less than the denominator then it is a common fraction as for example 3/4 and if the numerator is greater than the denominator then it is an improper fraction as for example 6/4
The denominator is the number underneath the numerator in a fraction as for example in the fraction 3/4 the numerator is 3 and the denominator is 4
