Answer:
57/40
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.
![(4)/(5) =(x)/(40) \\\\\\frac{5}{8} = (x)/(40)](https://img.qammunity.org/2023/formulas/mathematics/college/ql5dbjhoidfhdanvl9rb5fwr63ek6oeupq.png)
The new equation is this:
![(32)/(40) +(25)/(40)](https://img.qammunity.org/2023/formulas/mathematics/college/aaa968ho7tvnttydqwtr3k7ls027q0gche.png)
Now we use our common sense. 32+25=57
57/40.
