wizmantr5 3 years ago Find the ratio of x to y. x/5=2/3=5/y A. 2/3 B. 4/9 C. 1

1. waterineyes

Firstly equate x/5 = 2/3 Cross multiply it and then solve for x.. Can you do that???

2. wizmantr5

no???????????????????????

3. waterineyes

Or you can instead of multiplying simply mutiply the upper equation by 5 both the sides.. This you can work out or not??

4. wizmantr5

no????? im confused?

5. waterineyes

Multiply both the sides, what you get???

6. wizmantr5

what?

7. waterineyes

It is ok.. I will show you how to do this in a draw... |dw:1340295759878:dw| Getting or not???

8. wizmantr5

not?

9. waterineyes

Where you are facing problem just tell me...

10. waterineyes

Which step you are not getting tell me??

11. wizmantr5

um the whole thing im lost beneath this world and the next lol? :P

12. waterineyes

Want to learn how we solve these type of problems or you are simply interested in only the answer of the problem??

13. waterineyes

First step is to equate the first two things because they are given equal.. So, we have done : x/5 = 2/3 This step you got or not???

14. wizmantr5

idk?

15. waterineyes

What you don't know??

16. wizmantr5

any of it...... im dumb

17. waterineyes

See we are given : x/5 = 2/3 = 5/y Here we can equate any one of the three.. You can equate: x/5 = 2/3 Or you can equate: 5/y = 2/3 Or you can also equate: x/5 = 5/y.. This point is clear to you or not??

18. wizmantr5

yes :)

19. waterineyes

So, can you please concentrate tell me why I am first equating x/5 = 2/3?? Point it out or not??

20. wizmantr5

um to get rid of those and find the answer for that particular one?

21. waterineyes

Ha ha ha.. What is the question saying?? Concentrate on what we have to find.. We are to find x/y.. you will only be able to find x/y if you know the values of x and y else you can't.. So, by doing that I am finding the value of x.. Got or not??

22. wizmantr5

yeah

23. waterineyes

So, tell me how you will find : x/5 = 2/3 What will you do first??

24. wizmantr5

cross multiply by taking 2*5 and 3*x

25. wizmantr5

and that would be 10=3x then u divide by 3 and that would be 3.333333333333333

26. waterineyes

No no, you did right but do not take it in decimals, You got x = 10/3 Right???

27. wizmantr5

yes

28. waterineyes

For finding y value what will you equate???

29. wizmantr5

2/3=5/y

30. waterineyes

Oh great yaar you are getting it.. Then you will find y now.. What is y?? calculate hurry up..

31. RomeoRaj

x/5=2/3 x=10/3 5/y=2/3 y/5=3/2 y=15/2 therefore, x/y=(10/3) / (15/2) x/y=4/9

32. waterineyes

Don't look at the solution @wizmantr5 just solve it on your own..

33. wizmantr5

2*y and 5*3 that would be 15=2y then u divide by 2 and that would be 7.5

34. waterineyes

Don't go in decimals, See you got y = 15/2 Right???

35. wizmantr5

yeah so its 4/9?

36. waterineyes

After finding y what you did next??

37. wizmantr5

thats it

38. waterineyes

I think you after finding y just see the solution of RomeoRaj.. Did you??

39. wizmantr5

yeah

40. wizmantr5

ok

41. waterineyes

One thing You must remember, Seeing answers is not the problem, but the thing that matters is how we have come to that answer...

42. wizmantr5

ok
