To find the sum of [tex]\( \frac{2}{5} \)[/tex] and [tex]\( \frac{2}{4} \)[/tex], let's first identify their decimal equivalents:

[tex]\[ \frac{2}{5} = 0.4 \][/tex]
[tex]\[ \frac{2}{4} = 0.5 \][/tex]

Next, we add these two decimal values together:

[tex]\[ 0.4 + 0.5 = 0.9 \][/tex]

Now, we need to express this sum as a fraction in its simplest form.

We know that:

[tex]\[ 0.9 = \frac{9}{10} \][/tex]

Therefore, the sum of [tex]\( \frac{2}{5} \)[/tex] and [tex]\( \frac{2}{4} \)[/tex] is:

[tex]\[ \frac{9}{10} \][/tex]

So, the best answer to the given question is:

B. [tex]\( \frac{9}{10} \)[/tex]
