Question 1113273
<br>
To be able to solve this problem, we need to assume that each marriage is between one man and one woman.<br>
Assuming that, you need a common NUMERATOR for the two fractions.  So we can say that 6/9 of the men are married to 6/8 of the women.<br>
Then of every 17 people in the complex, there are 6 married couples; and there are 9-6=3 single men and 8-6=2 single women.  That makes 12 married and 5 single people.<br>
So the ratio of married people to the total adult population in the complex is 12:17.
