Hey there!
The easiest way I could think to do this is by converting your mixed number to an improper fraction and multiplying the fraction by 2, or 2 over 1.
[tex]6 \frac{2}{3} = 6*3+2 = \frac{20}{3} [/tex]
[tex]\frac{20}{3} * \frac{2}{1} [/tex]
To multiply fractions, you can just multiply the numerators and denominators and simplify, if applicable.
[tex]\frac{20}{3} * \frac{2}{1} = \frac{40}{3} [/tex]
Since you can't simplify this fraction in its improper form, just convert it back into a mixed number.
[tex] \frac{40}{3} = 13 \frac{1}{3} [/tex]
So, your answer will be [tex]13 \frac{1}{3} [/tex].
Hope this helped you out! :-)
