First make it that both denominators are the same.
[tex] (\frac{1}{2} \times 5) + ( \frac{2}{5} \times 2) = \frac{5}{10} + \frac{4}{10} [/tex]
Then add both numerators
[tex] \frac{5}{10} + \frac{4}{10} = \frac{9}{10} [/tex]
Your final answer should be
[tex] \frac{9}{10} [/tex]

[tex]\frac{1}{5}[/tex]

[tex]\frac{1}{2}[/tex] × [tex]\frac{2}{5}[/tex]

= [tex]\frac{1(2)}{2(5)}[/tex] = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex] in simplest form ( cancelling 2 and 10 by 2 )
