## amber15 2 years ago In an American sign language(ASL) class of 24 students ,5 are hearing impaired. what is the ratio of hearing impaired students to the total number of students

1. e.mccormick

Do you know how ratios work?

2. amber15

no

3. e.mccormick

Looks like they are taking the site down soon for maintenance. Here is a reference: http://www.purplemath.com/modules/ratio.htm http://www.mathsisfun.com/definitions/ratio.html or two.

4. amber15

okay thank you

5. e.mccormick

For a simple ratio, it is a lot like a fraction. When there are more than two things, it gets more complex than that.

6. amber15

oh okay

7. e.mccormick

That part, "hearing impaired students to the total number of students" determines the order of the ratio.

8. e.mccormick

A to B means A on top, B on the bottom.

9. amber15

oh okay

10. e.mccormick

Norally I'd take time, go over it nice and slow, make sure you got all the points. But that might take more than the 20 min we have, so there is the short version and some references! I hope it is enough.

11. amber15

it's okay i hope i figure it out

12. e.mccormick

Well, both the references have clear examples. They should do a pretty good job of making this clear to you.

13. amber15

thank you

14. amber15

it wouldnt be 4/25 would it

15. e.mccormick

It would.

16. e.mccormick

Or, 5/24. Hehe. Transposed some numbers!

17. amber15

okay

18. e.mccormick

Yah, now, if the numbers can reduce, like in a fraction, that is allowed. So 3/12 is 1/4.

19. amber15

it dont want me simplify

20. e.mccormick

If it was complec, it woulld be things like, "In a bag of marbles there are six red, three green, and 1 blue. What is their ratio?" 6:3:1

21. e.mccormick

Yah, with 5/24, there is nothing to simplify. 5 is prime and 24 is not a multiple of 5.

22. amber15

so my answer would be right i hope 5/24

23. e.mccormick

5/24 is right. Sometimes they want it written 5:24, but both are right. If they did not specify, 5/24 is more common.

24. amber15

they want it in fraction

25. e.mccormick

Then that is 100% right!

26. amber15

thank you

27. e.mccormick

np. have fun!
