The police department in mansville employs 54 men and 36 women. what percent of the total are men? what is the answer to this question, and how do i set it up as a proportion?

The answer to this question is that 60% of the police department are men. 
To set it up, have  =  as 54 plus 36 equals 90. Multiplay 54 by 100 and then divide the product by 90 to get the pecent.

I'm not sure exactly but my best guess would be 1/4
