Question

What is the value of the expression

0.5 + (-3/4) + 0.25 - (-4/5)

Explain your answer

Answer 1

0.8

Explanation:

We begin with the expression:
`0.5+(-(3)/(4) )+0.25-(-(4)/(5) )`

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

`-(3)/(4)=-0.75` and
`-(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`
