Final answer:
Using the ratio of men to women as 91.5, which can also be shown as 6:1, and knowing there are 63 men, the proportion is set up as 6:1 = 63:x, resulting in 10.5 women for the given number of men.
Step-by-step explanation:
The question asks to determine the number of women present given that the ratio of men to women is 91.5 and there are 63 men. To solve this, we will use a proportion where the number of women is represented by 'x'.
The ratio 91.5 can also be represented as 9:1.5 or equivalently as 6:1 since ratios can be scaled by a common factor, in this case, dividing both numbers by 1.5.
We can set up the proportion as:
9/1.5 = 63/x
Now, by cross-multiplying to solve for x, we get:
9x = 63 * 1.5
9x = 94.5
x = 94.5 / 9
x = 10.5
Therefore, there are 10.5 women when there are 63 men given the ratio is 91.5.
