Answer:
There are 48 women (method is below).
5+4=9. The ratio is 5:4, so the total number of 'parts' that that the 108 is split into is 9.
108/9=12. So each 'part' of the ratio is worth 12.
12*4=48. The 9 'parts' are allocated in a ratio of 5:4, so the total number of women is 4 times the value of 1 part.
I'm not sure how well I explained that but hopefully it helps.
