Answer:

57/40

Step-by-step explanation:

So we need to find the LCD, or the least common denominator.  The LCD is 40.  Now, we do a transition to find the new numerator.

[tex]\frac{4}{5} =\frac{x}{40} \\\\\\frac{5}{8} = \frac{x}{40}[/tex]

The new equation is this:

[tex]\frac{32}{40} +\frac{25}{40}[/tex]

Now we use our common sense.  32+25=57

57/40.

You can't simplify this...
