Question

What is the value of the expression below? (4/5+3/5)+3.5*5

Answer 1

Step-by-step explanation:

(4/5+3/5)+3.5*5

= 7/5+7/2*5

= 7/5+35/2

= 14/10+175/10

= 189/10

= 18.9

Answer 2

Answer:

The value of the expression is 18.9

Step-by-step explanation:

The expression is:

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

The first step is to solve the parenthesis. As both fractions have the same denominator, the numerators must be added:

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

$\bigg( \frac{7}{5}\bigg)+3.5\times 5$

The second step is to perform the division between 7 and 5, it is 1.4:

$1.4+3.5\times 5$

The third step is to perform the multiplication between 3.5 and 5, it is 17.5:

$1.4+17.5$

The last step is to perform the sum, it is 18.9:

$1.4+17.5=18.9$

Thus, the value of the expression is 18.9.
