I have a question about whole number fraction like (1/1, 2/2, 3/3, 4/4, 5,5) why do we call them Improper fraction. Because we can see that Numerator and Denumerator is same then we can call them by whole fraction, but why do we call them improper fraction, though the definition indicates value should be equal to 1 or more than 1. Do you have any reference about this question?
