To add the fractions we need to remember the following rule:
[tex]\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}[/tex]In this case we have a=2, b=8, c=1 and d=10; then we have:
[tex]\begin{gathered} \frac{2}{8}+\frac{1}{10}=\frac{20+8}{80} \\ =\frac{28}{80} \\ =\frac{7}{20} \end{gathered}[/tex]Therefore the final result is 7/20.
