$18.9=18\frac{9}{10}$

Step-by-step explanation:

The given expresion is

$(\frac{4}{5}+\frac{3}{5})+3.5 \times 5$

To solve this expression, we must apply the right hierarchy of operations. First, we must solve products and then we solve sums and differences.

$(\frac{4}{5}+\frac{3}{5})+17.5$

Then, we solve fraction sums

$\frac{4+3}{5}+17.5=\frac{7}{5}+17.5$

Now, we can sum

$\frac{7}{5}+17.5=\frac{7+87.5}{5} =\frac{94.5}{5}=18.9$

Which is equal to

$18.9=18\frac{9}{10}$

Therefore, the right answer is the second hoice.
