Answer:
[tex]18.9=18\frac{9}{10}[/tex]
Step-by-step explanation:
The given expresion is
[tex](\frac{4}{5}+\frac{3}{5})+3.5 \times 5[/tex]
To solve this expression, we must apply the right hierarchy of operations. First, we must solve products and then we solve sums and differences.
[tex](\frac{4}{5}+\frac{3}{5})+17.5[/tex]
Then, we solve fraction sums
[tex]\frac{4+3}{5}+17.5=\frac{7}{5}+17.5[/tex]
Now, we can sum
[tex]\frac{7}{5}+17.5=\frac{7+87.5}{5} =\frac{94.5}{5}=18.9[/tex]
Which is equal to
[tex]18.9=18\frac{9}{10}[/tex]
Therefore, the right answer is the second hoice.
