Fter completing the fraction division 7/3 : 2/9 , Bai used the multiplication below to check his work.
Vitek1552 [10]
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.
