Equivalence can be used to make fractions easier to compare. For instance, to use the common denominator strategy to compare 2/5 and 3/8, each fraction can be rewritten as an equivalent fraction with a denominator of 40. Once the denominators are the same, one can simply compare the size of the resulting numerators.
