“Men outnumbered women by a ratio of 9 to 5” A. There were four more men then women B. the number of men was 1.8 times under the women C. The number of men divided by the number of women was equal to the quotient of 5 divided 9 D. In the stadium, five out of nine were fans were women

A. When saying there were "4 more men than women", this does not equal a ratio because the same could be true for 14 men and 10 women, which is not a ratio of 9:5

B. Men being 1.8 times under the women would give us an equation similar to this: 1.8m = w Now considering that 9:5 as a fraction does come out to 1.8, this gives potential to accuracy seeing as anything plugged in would automatically be factored through the ratio.

C. Is essentially saying: m/w = 5/9 which would be opposite to the ratio before us, stating men to be more than women. If they were reversed, this answer would be correct.

D. When having 5 out of 9 fans being women, this would mean that the other 4 were men. To correct this statement to make it true, it would have to be "5 out of 14 fans were women"

So after thorough explanation, we can confidently conclude that B is the correct answer. Hope this helped :)
