1. iforgot

if you get a score on you paper it is written like how?

2. iforgot

i mean sometimes not all

3. iforgot

you might see a 98 meaning you got 98 questions correct out of 100 ---- 100 coicedentally it also means that you got 98 percent as you score

4. iforgot

calculate it as you see it :P

5. Selena2345

i don't understand what you wrote

6. iforgot

98 --- 100 98 divided by 100 ?

7. iforgot

i spelled coincidentally wrong :P

8. Selena2345

98/100=0.98

9. iforgot

then for percentage you must move the decimal place 2 spaces back

10. iforgot

95%

11. Selena2345

12. iforgot

to get a decimal numeric value move 2 spaces foward

13. Selena2345

can you give me the answer @iforgot

14. lillybeth123

the answer souldnt be a decimal or percentage, 1 min

15. iforgot

16. Selena2345

okay @lillybeth123

17. iforgot

but do you know how calculate percentage problems back and forth?

18. Selena2345

no

19. iforgot

20. iforgot

that is what the question was asking

21. Selena2345

22. iforgot

23. iforgot

it will be too confusing doing 2 things at once

24. lillybeth123

i can look it up later, but im in a quiz, ill tell you the answer in a bit.

25. iforgot

ok back to my example this is a given situation TEST SCORE 98 --- 100

26. iforgot

This means that 98 --- 100 <--- number of test problems

27. iforgot

98 <--- number test problems correct --- 100 <--- number test problems

28. lillybeth123

i don't see wat 98 has to do with her problem.

29. iforgot

if you see my posts this is an example

30. iforgot

she/he has said that they are not very clear on percentage calculation

31. iforgot

98 <--- % out of --- 100 <--- number of problems this is synonymous when it is # % out of #

32. shevron

i think she/he has to say $\frac{ 85 }{ 100 }$ and multiply it by 60

33. iforgot

as i said in my examples 98 < --- correct --- = percentage yield 100 <--- # prob. you want # correct simple 60 <--- #prob --- = correct 85 <--- percent yield

34. iforgot

use what you want to solve for

35. iforgot

@Selena2345 do you understand y i am doing this?

36. Selena2345

no

37. iforgot

do you understand 98 --- = 98 % 100

38. iforgot

?

39. iforgot

"point" 98 (or any number) becomes a percent when the decimal space is moved back 2 places .98

40. iforgot

therefore 98 --- = .98 = 98% 100

41. iforgot

@Selena2345 you understand that?

42. iforgot

if i had 1 it becomes 100% 1.5 it becomes 150% .25 it becomes 25%
