to simplify when you divide two fractions you can invert the second and multiply, I will use this way for the first part of the equation,so
[tex]\frac{2}{7}\times\frac{14}{3}+\frac{2}{3}[/tex]First , do the multiplication
[tex]\begin{gathered} \frac{2\times14}{7\times3}+\frac{2}{3} \\ \\ \frac{28}{21}+\frac{2}{3} \end{gathered}[/tex]and now the sum
[tex]\begin{gathered} \frac{(3\times28)+(2\times21)}{21\times3} \\ \\ \frac{84+42}{63} \\ \\ \frac{126}{63} \end{gathered}[/tex]simplifying to each side by 63
[tex]\frac{2}{1}=2[/tex]the solution is 2
