Find the total people
can you finish the problem........
Assume that there are 10 women in the room, of which \(10 \times \frac{2}{5}\)=4 are single and 10-4=6 are married. Each married woman came with her husband,
so there are 6 married men in the room
Total man=10+6=16 people
Now The fraction of the people that are married men is \(\frac{6}{16}=\frac{3}{8}\)
