Answer:

$\frac{13}{20}$

Step-by-step 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:

$\frac{3}{5} * 8 = \frac{24}{40}$

$\frac{6}{8} * 5 = \frac{30}{40}$

$\frac{24}{40} + \frac{30}{40} = \frac{54}{40}$

We can also show 2 brownies as $\frac{2}{1}$ or $\frac{80}{40}$

Now we can subtract the two:

$\frac{80}{40} - \frac{54}{40} = \frac{26}{40}$

Simplify the fraction down by dividing by two:

$\frac{13}{20}$

Which is the fraction of brownie left!

Hope this helps!
