Answer:
5-10(0.8-3/5) = 3
Step-by-step explanation:
We need to Simplify the following expression: 5-10(0.8-3/5)
First, we need to solve the parenthesis. Given that we need to substract a fraction from a decimal number, we convert the number '0.8' to a fraction as follows:
[tex]0.8 = \frac{8}{10} = \frac{4}{5}[/tex]
Now we solve the parenthesis:
[tex](0.8 - \frac{3}{5})[/tex] ⇒ [tex]\frac{4}{5} - \frac{3}{5} = \frac{1}{5} [/tex]
The new expression is:
[tex]5-10(\frac{1}{5}) [/tex] ⇒ [tex]5-2 [/tex] ⇒ 3
Therefore, 5-10(0.8-3/5) = 3
