What is a fraction?


A fraction is part of a whole.


It is expressed as a top number (the numerator or part) divided by a bottom number (the denominator or whole).



Example 


Say you eat one slice of a pizza which has been divided into four equal slices.



The numerator or part is the one slice of pizza you have eaten.


The denominator or whole is the original four slices of pizza.


So the fraction of pizza eaten is



- one quarter
