Mastering Benchmark Fractions for Grades 4-5

Why can't we use the strategy of comparing like numerators or denominators for all fractions?

• Because it only works for fractions with unlike denominators

• Because it is an outdated method

• Because it is too complicated

• Because not all fractions have the same numerators or denominators
