Answer:
[tex]\large{\mathbf{\frac{9}{10}}}[/tex]
Step-by-step explanation:
[tex]\frac{2}{5} +\frac{2}{4}[/tex]
The two fractions have different bottom numbers ,so we have to unify the denominators :
[tex]\frac{2}{5} +\frac{2}{4} =\frac{2\times4 }{5\times 4} +\frac{2\times5}{4\times5}[/tex]
[tex]=\frac{8 }{20} +\frac{10}{20}[/tex]
[tex]=\frac{8+10 }{20}[/tex]
[tex]=\frac{18 }{20}[/tex]
[tex]=\frac{18\ :\ 2 }{20 \ : \ 2}[/tex]
[tex]= \frac{9}{10}[/tex]
