We would first need to figure out how many women there are in order to know about the number of men.
5c = w (women)
3w = m (men)
There are 730 children and to find out the number of women we need to do

where w = 3650
There are 3650 women. TO figure out the number of men, we need to do

where m = 10950
Therefore, the number of men in the mall is 10,950.
