Answer:
67/45
Step-by-step explanation:
3/5 + 8/9
The first step is to make the denominators equal. And to make them equal, we find their LCM (lowest common multiple).
LCM of 5 and 9 :
5 = 5 x 1
9 = 3 x 3
They don't have any common factor. Hence, we can directly multiply 5 and 9. We get 5 x 9 = 45.
3/5 + 8/9
= {(3 x 9) + (8 x 5)} / 45
= {27 + 40} / 45
= 67/45
Thus, 67/45 is the sum of 3/5 and 8/9.
