The calculation is

[tex]4\cdot\frac{2}{3}+\frac{7}{9}[/tex]

First step is to solve the multiplication.

4 means that there are four wholes, if you express in in thirds

[tex]\begin{gathered} 1\text{whole}=\frac{3}{3} \\ 4\text{wholes}=\frac{3\cdot4}{3}=\frac{12}{3} \end{gathered}[/tex]

Then the multiplication you have to do is

[tex]\frac{12}{3}\cdot\frac{2}{3}=\frac{8}{3}[/tex]

Now that the multiplication is done add 7/9

[tex]\frac{8}{3}+\frac{7}{9}=\frac{31}{9}[/tex]
