Answer 2

First off all, let's find 
$\dfrac{7}{3} : \dfrac{2}{9} = \dfrac{7}{3} \cdot \dfrac{9}{2}= \dfrac{63}{6} = \dfrac{21}{2}$.

This shows that Bai found the correct quotient.

If $a:b=c$, then $a=c\cdot b$. Using this rule, you have to check that $\dfrac{7}{3}$ is equal to product  $\dfrac{21}{2} \cdot \dfrac{2}{9}$. 

Thus, Bai checked his work using multiplication correctly.

Answer: Correct choice is A.
