Question

What is the answer to this problem?

Answer 1

`(7)/(9)`

Explanation:

If you add a number that is negative, you are basically subtracting it.

This means that

`(8)/(9)+\left(-(1)/(9)\right)=(8)/(9)-(1)/(9)`

Since they both have the same denominator, you can easily subtract the fractions:
`(8-1)/(9)=(7)/(9)`
