Answer:

`(13)/(20)`

Explanation:

First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:

`(3)/(5) * 8 = (24)/(40)`

`(6)/(8) * 5 = (30)/(40)`

`(24)/(40) + (30)/(40) = (54)/(40)`

We can also show 2 brownies as
`(2)/(1)` or
`(80)/(40)`

Now we can subtract the two:

`(80)/(40) -  (54)/(40) = (26)/(40)`

Simplify the fraction down by dividing by two:

`(13)/(20)`

Which is the fraction of brownie left!

Hope this helps!
