SOLUTION :
[tex]\color{red}5 \frac{1}{2} - - - - - \: 2 \\ \color{blue} + \frac{2}{5} - - - - - \: 5[/tex]
[tex] \sf\color{red}2 \: and \: 5 \: are \: \\ \sf\color{blue}different \: denominators[/tex]
[tex] \color{red}5 \frac{1}{2} = 5 \frac{5}{10} - - - - - - LCD \\ \color{blue} + \: \frac{2}{5} \times \frac{2}{2} = \frac{4}{10} - - - - - - LCD \\ \sf \color{red}10 \: and \sf \color{blue} \: 10 \: is \: LCD[/tex]
[tex] \color{red}5 \frac{1}{2} = 5 \frac{5}{10} \\\color{blue} + \: \frac{2}{5} = \frac{4}{10} \\[/tex]
