What is the difference between denominator and numerator? 

Answer 1: Denominator is when we have a fraction, this will be the number at the bottom, and the numerator is the number at the top of the fraction. An example of that is 3/5.

It is important to know the difference because if they are put the other way around, the result will be com

Answer 2: In any fraction, numerator is the top number and the denominator is the bottom one. Example can be 5/4 or 1/6
