What is the value of the expression

Y_Kistochka [10]

Answer:

0.8

Step-by-step explanation:

We begin with the expression: $0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )$

First, we need to convert the fractions into decimals to make this easier.

$-\frac{3}{4}=-0.75$ and $-\frac{4}{5} =-0.8$

Once we have this, we can simplify it

$0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8$
