There are 35 females performed in a dance recital. the ratio of men to women is 3 : 8. how many men are in the dance recital

13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.

Step-by-step explanation:

Be careful how you interpret this question. It reads like this.

3:8 :: x:35

In other words, the 8 and 35 females goes together.

Set this up as a proportion

3/8 = x / 35  Cross multiply

3*35 = 8x     Combine the left

105 = 8x       Switch

8x = 105        Divide by 8

x = 105 / 8     get the answer

x = 13.125       You cannot have 1/8 of a person. So what are you going to do?

You have to round down. x = 13. How close is this

13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.

yes. we do proportions in probabilities.
