Answer:
0.8
Step-by-step explanation:
We begin with the expression: [tex]0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )[/tex]
First, we need to convert the fractions into decimals to make this easier.
[tex]-\frac{3}{4}=-0.75[/tex] and [tex]-\frac{4}{5} =-0.8[/tex]
Once we have this, we can simplify it
[tex]0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8[/tex]
