look at this

$5\dfrac 2 3 \times \dfrac 1 6 =\\ \left(5 + \dfrac 2 3\right) \times \dfrac 1 6 = \\ 5 \times \dfrac 1 6 + \dfrac 2 3 \times \dfrac 1 6 = \\ \dfrac 5 6 + \dfrac 1 9 = \dfrac {15}{18}+\dfrac {2}{18} = \dfrac {17}{18}$

Go on google then put in 5 2/3 x 1/6 just like that with the slash marks and everything =)
