Blankenship · Answer 1

The least common multiple of 8 and 9 is 72.

2/8 x (9/9) = 18/72

3/9 x (8/8) = 24/72

Roberto Garrison · Answer 2

We can convert both of them to denominators of 72.

2 * 9 = 18

8 * 9 = 72

3 * 8 = 24

9 * 8 = 72

So we have:

18/72 + 24/72

Then we just add the numerators.
