Looking for Math Geniuses!

On that TEAS test I took yesterday there were 4 math problems that were all similar that are not in the study guide and I cannot locate on any math help web-site so far. I was hoping that some braniac here could help me figure it out.

It was set up like a ratio - but yet it was different. The one I remember exactly was:

1/1000:1/50=x/6 - solve for x...maybe this is really easy and I am just reading too much into it - but it doesn't make sense to me.

Thanks in advance to anyone that can help.

brainiac :rotfl: sorry I'm not one of those :chuckle

Stdy2BaNurse:

The Pre-nursing student forum has a math help links thread.

:) Same page as your thread. Hope it helps.

I'm not really a brainiac, but I do know how to solve this:

1/1000: 1/50= X/6

First take 1/1000 and simplify (just divide 1 by 1000) and get 0.001.

Now take 1/50 and simplify to get 0.02.

You are left with the ratio 0.001 : 0.02. A ratio is the same as a fraction, so what you have here is really 0.001/0.02. Divide again to get 0.05.

Now the formula is reduced to 0.05=X/6. We want to isolate X so multiply X/6 by the denominator 6 and then multiply the left side of the equation by 6. ( 6 x 0.05 = X/6 x 6/1) 0.3=X so that's your answer!

i would not be exaggerating to say you both are my heros! now that you have worked it out - it doesn't seem so difficult. however, when faced with it in a test situation when i have never seen anything like that before - i freaked!

thank you sooooo much - both of you!!

let me know how if i can return the favor - i have a good ear for listening :)
