Explain how you know 21/30 is greater than 2/3
Luba_88 [7]
Simple.

to figure out if they are either: equal, greater, or smaller...

First, find a common denominator...

\frac{21}{30}

and

\frac{2}{3} * \frac{10}{10} = \frac{20}{30}

Now, we can obviously make the assumption that \frac{21}{30} is greater than \frac{20}{30}.

Thus, your answer.
