`3`$\frac{2}{3}$ × `1`$\frac{1}{3}$ + $\frac{4}{3}$ × $\frac{1}{3}$
= $\frac{11}{3}$ × $\frac{4}{3}$ + $\frac{4}{3}$ × $\frac{1}{3}$
= ( $\frac{11}{3}$ + $\frac{1}{3}$ ) × $\frac{4}{3}$
= `4` × $\frac{4}{3}$
= $\frac{16}{3}$

`3 2/3 xx 1 1/3 + 4/3 xx 1/3`
`= 3 2/3 xx 4/3 + 4/3 xx 1/3`
`= 4/3 xx ( 3 2/3 + 1/3 )`
`= 4/3 xx 4`
`= 16/3`
