Verified Answer :

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.

if you do 2 X 10, it's 20.
if you do 3 X 10, it's 30.

so, the fraction would be 20/30, and with the denominators the same, now you can see that 21 is greater than 20.

hopes this helps (:
