Rules of Comparing Fractions:
1. For fractions with the same denominator... the greater numerator indicates the greater fraction.
example: 3/5 > 2/5 because 3>2.
2. For fractions with the same numerator... the lesser denominator indicates the greater fraction.
example: 1/3 > 1/5 because 3 < 5.
Think of slices of pie. If your mom cuts a pie into 3 slices and gives you 1 slice, that is larger than 1 out of 5 slices.
