Proportion practice:
"Fancy factory has 300 employees with a 3 to 7 ratio of men to women. How many men work there?"
I've been working on this forever. And I can't figure out what to do. DX uarrghhh. Help?
You could set up a proportion:
7/10 = x/300
10x = 2100
x = 210
if you mean there are 3 men to 7 women, then the answer is 90 men to 210 women.
if you mean there are 3 women to 7 men, then it's 210 men and 90 women.
But how did you get E.G? that I'm sorry but I don't understand. [hitshead]
Ms. Sue, how did you get 7/10, when there is 7:3 women to men? (confused)
I'm afraid my system is very primitive.
What I did is add 3+7 = 10
then I divided 300 by 10 = 30
then I multiplied 3 x 30 = 90
and 7x30 = 210
I am certain that Ms. Sue can explain that a lot better and much more professional that I can.
Sure, I can help you with that! In order to find out how many men work at the Fancy factory, we need to use the given ratio of 3 to 7.
First, let's break down the ratio into parts. Since the total ratio is 3 + 7 = 10, we can say that 3 out of 10 represents the number of men at the factory. Similarly, 7 out of 10 represents the number of women.
Now, we can set up a proportion to find the number of men.
Let 'x' be the number of men at the factory. We can set up the following proportion:
3/10 = x/300
To solve for 'x', we can cross multiply:
3 * 300 = 10 * x
900 = 10x
Dividing both sides by 10 gives us:
900/10 = x
Therefore, x = 90.
So, there are 90 men who work at the Fancy factory.
