Question

The number of men is 3 times the number of woman. The number of women is 5 times the number of children at the mall

Answer 1

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 
$5 \times 730 = w$
where w = 3650 

There are 3650 women. TO figure out the number of men, we need to do $3 \times 3650 = m$
where m = 10950

Therefore, the number of men in the mall is 10,950.
