Proper Fractions

Proper Fractions
Definition : A proper fraction is a fraction with a smaller numerator then denominator.

Names used in fractions:
numerator - is the number to the left of the line. In the fraction 7/8 the numerator is 7.
denominator - is the number to the right of the line. In the fraction 7/8 the denominator is 8.

Proportional Fractions - At the beginning of this page we defined the word fraction as a portion of the whole. We have shown that there is more than one way to write the portion that is half of the pizza. One half can be written as 4/8, 2/4 or 1/2. We say that these equivalent fractions are proportional fractions because they are the same portion of the pizza. Here are some different examples of proportional fractions using the integer bars. All of them are equivalent.
