How do I use benchmark fractions

1 answer:

5 0

Compare fractions using a benchmark fraction. Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole.
