1/3 is more than 1/4 because if the numerators are the
same, you look at the denominators. The one with the
smaller denominator is the larger fraction because you
did not divide the pieces up as much, therefore the
pieces are bigger.
Discuss
Eric because 1/5 is greater than 1/7
Lucy because 2 out of 6 is more than 2 out of 8.
