Answer :

You have problem which looks like this
[tex]6 \frac{2}{3} * 3\frac{3}{10} [/tex]
To multiply fraction we have to transform into improper fractions
[tex] \frac{20}{3}* \frac{33}{10} [/tex]
We can reduce 3 and 33 by cross reducing and 10 and 20
[tex] \frac{2}{1} * \frac{11}{1} =2*11=22[/tex] - its the result.

[tex] 6\frac{2}{3}=\frac{20}{3} \\ \\3\frac{3}{10}=\frac{33}{10} \\ \\ \frac{20}{3} *\frac{33}{10} = \frac{660}{30} =22 \\\\\boxed{22}[/tex]
