Now you can reduce the fraction  :

 And make the corresponding addition: in this case the Least Common Denominator (LCD) will be the multiplication of the denominators.   Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then add the products. Therefore you get:
