8%2F%283mn%5E2%29%22%22%2B%22%22k%2F%28m%5E3n%29

LCD+=+3m%5E3n%5E2

The first fraction's denominator needs to be multiplied by m%5E2
in order to become the LCD, so we multiply the first fraction by red%28%28m%5E2%2Fm%5E2%29%29.

The second fraction's denominator needs to be multiplied by 3n
in order to become the LCD, so we multiply the second fraction by red%28%283n%2F%283n%29%29%29.

expr%288%2F%283mn%5E2%29%29%2Ared%28%28m%5E2%2Fm%5E2%29%29%22%22%2B%22%22expr%28k%2F%28m%5E3n%29%29%2Ared%28%283n%2F%283n%29%29%29

 8m%5E2%2F%283m%5E3n%5E2%29%22%22%2B%22%223nk%2F%283m%5E3n%5E2%29

Combine numerators over the LCD:

 %288m%5E2%2B3nk%29%2F%283m%5E3n%5E2%29
