Comparing and Ordering Fractions

Two Helpful Rules for Comparing Fractions

Hello,
I mention these in the accompanying video, but I wanted to have them in print as well. So here goes:

LIKE NUMERATORS
To have like numerators means that two or more fractions have the same numerator (top number). When comparing fractions with like numbers, follow these steps:
1) Make sure the numerators are the same.
2) Look at the denominators (bottom numbers)
3) The fraction with the larger denominator is the SMALLER fraction. Again, the fraction with the larger denominator is the SMALLER fraction.

Example:
2/5 and 2/9
They both have 2 in the numerator. So I look at the denominators. 9 is the larger denominator, so 2/9 is the SMALLER fraction. Therefore, 2/5 is greater than 2/9.

LIKE DENOMINATORS
To have like denominators means that two or more fractions have the same denominator (bottom number). When comparing fractions with like denominators use these steps:
1) Make sure the denominators are the same.
2) Look at the numerators
3) The fraction with the smaller numerator is the SMALLER fraction.

Example:
3/8 and 5/8
They both have 8 in the denominator. So I look at the numerators. 3 is the smaller numerator, so 3/8 is the smaller fraction. Therefore, 3/8 is less than 5/8.
