Multiplying the numerator and denominator by the same number will result in an equivalent fraction. We multiply the numerator and denominator each by 2 because 2 x 2 = 4 • = Multiplying by is the same as multiplying by 1. Thus has the same value as . It is not necessary to rename since it already has a denominator of 4. Add the numerators.

By sorting fractions in our heads according to how close they are to 0, 1/2, or 1 whole, it becomes easy to compare fractions that have different denominators. The discussion also included the fact that when we are comparing fractions, we do so knowing that the whole is always the same size (in other words when we compare 2/5 of a pizza to 5/8 ...
