## lgbasallote 3 years ago The ratio of helper to learner in OpenStudy is 1:20 during regular time. Over the summer, the total population of OpenStudy decreased by 32%. What will be the ratio of helper to learner in the new population?

haha got to love this question! 1:12

2. lgbasallote

how?

3. saifoo.khan

I think we will find the 32% of 21 first.

4. saifoo.khan

i mean decrease 32 %/

5. lgbasallote

21 is the totalright?

6. lgbasallote

total ratio i mean

7. saifoo.khan

No. 20+1 = 21 So Yes. lol.

8. saifoo.khan

6.72 decreased.

9. saifoo.khan

21 - 6.72 = 14.28

10. saifoo.khan

idk how to continue from here.

11. lgbasallote

hah lol

12. saifoo.khan

@dpaInc , try this out!

13. saifoo.khan

im not sure but i will try it out, 1/21 * 100 = 4.76% were the helpers. ON TOTAL. And since the total popl decreased, the ratio should remain the same (i think) Next, thinking..

14. dpaInc

thing is... is that 32% include the helpers? when u say a decrease total of 32%, i'm assuming the whole population so shouldn't the ratio still be 1:20? idk... :(

15. lgbasallote

so it;s still same?

16. dpaInc

is the 32% decrease only the ones being helped? if yes, then it wouldn't be the same...

17. saifoo.khan

@lgbasallote , so you asked a wrong question! D:

18. saifoo.khan

@dpaInc 's way seems legit.

19. lgbasallote

lol i just copied it from my book :P blame the book

20. dpaInc

umm don't bank on my answer... i only puking out what i think...:)

21. saifoo.khan

Books are waste of trees. Dont buy them.

22. irfans

Ratio will remain same even after reduction in total population , assuming reduction is uniform across the population.

23. dpaInc

what' happens when we get a an electromagnetic pulse from the nuclear warheads? all those hard drives will be wiped clean... so books are good...:)

24. yakeyglee

The ratio will be unchanged!

25. dpaInc

watch the move "Book of Eli".... good story...
