Answer:
B
Explanation:
A - incorrect because what if there were 18 men and 10 women, same ratio but 8 more men not 4.
B- yes because 5 * 1.8 = 9, 10 * 1.8 = 18, and no matter what, the number of women * 1.8 = the number of men
C- no, no idea where the quotient of 5 came out of
D- no because then the ration would have been 4 men to 5 women.
