The top number of a proper fraction (called the numerator) is less than the bottom number (called the denominator).
Dictionary DefinitionThe Oxford English Dictionary defines a proper fraction as "a fraction whose magnitude is less than one, the numerator being lower in magnitude than the denominator."
Examples of Proper FractionsHere are some examples of proper fractions:
Visualizing Proper FractionsA useful way of visualizing fractions is to picture it as a cake being cut into equal parts.
The top number (the numerator) tells you have many slices you have. The bottom number (the denominator) tells you how many equal slices the cake is cut into.
For proper fractions, there are not enough slices to make a whole cake:

The Size of Proper FractionsThe size of a proper fraction is always less than 1.
We visualize this by noticing there are never enough slices to make a cake.
