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

okay 95% is the answer

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

an answer to that example

16. Selena2345

okay @lillybeth123

17. iforgot

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

18. Selena2345

no

19. iforgot

the answer should be a number of questions correctly answered

20. iforgot

that is what the question was asking

21. Selena2345

what is the answer @iforgot

22. iforgot

lets finish your question first...

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%

43. iforgot

@Selena2345 you follow with that?
