## anonymous 5 years ago what are 5 fractions for 75%

1. anonymous

hello?

2. anonymous

hello

3. anonymous

well, ok, will start you off, what is 75%?

4. anonymous

as a fraction

5. anonymous

trust me - I know you want to get this done, but it will be much faster to learn it

6. anonymous

2 out of 3?

7. anonymous

well, so when you see a %, you can start by thinking how many out of a 100

8. anonymous

so 75% is 75/100

9. anonymous

wait wait 3 out of 4

10. anonymous

so if I say 75% of people love fractions, exactly!

11. anonymous

yes 3/4 is 75%

12. anonymous

and by definition, 75/100 is 75%

13. anonymous

so you can follow the same strategy as before

14. anonymous

you can either start at 75/100 and reduce

15. anonymous

by reduce I mean you can evenly divide both the top and bottom by the same number

16. anonymous

or you can start at 3/4 and multiply

17. anonymous

ok

18. anonymous

so go ahead and try, and I'll check it for you

19. anonymous

but on a conceptual level - 75% basically means out of say 100 people, 75 people will do X

20. anonymous

wait what do i multiply

21. anonymous

well, just like last time, you started with 2/3

22. anonymous

and multiplied it by 2/2-6/6

23. anonymous

you can start at 3/4, and multiply by 2/2 - 6/6

24. anonymous

now the reason you can do this, is because 2/2, 3/3, 4/4, 5/5, 6/6, they're all actually equal to 1

25. anonymous

k

26. anonymous

and multiplying ANYTHING by 1, gets the same basic thing (hence "equivalent")

27. anonymous

so you're really just multiplying by 1 in different but "equivalent" ways

28. anonymous

1.6/8

29. anonymous

correct

30. anonymous

yay

31. anonymous

=)

32. anonymous

um so the next one would be 3/4 and 3/3

33. anonymous

hmmm, well, those are not equal to 1

34. anonymous

3/4 is 75%

35. anonymous

or .75

36. anonymous

it's only equivalent if you multiply the original fraction by 1

37. anonymous

since 2x1 = 2, 3x1 = 3 etc... anything multiplied by 1 = 1

38. anonymous

now fraction wise, the definition of "1" is something divided by itself

39. anonymous

so 1/1, 2/2, 3/3, 4/4, 5/5....

40. anonymous

those are all equal to 1

41. anonymous

and so if you multiple the original fraction by any of those, you'll have an equivalent fraction (since you've just multiplied by 1)

42. anonymous

but it may look different, since there are bigger numbers on the top and the bottom

43. anonymous

so the first one you did was correct, you multiplied by 2/2

44. anonymous

now you want to multiply by 3/3 and on

45. anonymous

so i multiply 3/4 and 3/3

46. anonymous

oh sorry lol

47. anonymous

I was still stuck on the last question

48. anonymous

which was 2/3

49. anonymous

yes!

50. anonymous

you are in fact right haha

51. anonymous

sorry =)

52. anonymous

its ok

53. anonymous

9/12!

54. anonymous

yes! =)

55. anonymous

yay

56. anonymous

and ps, you can check these by plugging them into your calculator

57. anonymous

3/4 and 4/4

58. anonymous

75% can also be written as .75

59. anonymous

because 75/100 is .75

60. anonymous

(move the decimal places two to the left)

61. anonymous

so every fraction you give me, if you put it in your calculator and divide, should equal .75

62. anonymous

63. anonymous

correct =)

64. anonymous

wow lol=)

65. anonymous

so if you divide 12 by 16 in your calculator, you will get .75

66. anonymous

thats incredible

67. anonymous

it makes a lot of sense once you practice =). and that's when math starts getting fun - once it finally makes sense

68. anonymous

so keep going =)

69. anonymous

ok

70. anonymous

15/20!!!

71. anonymous

mhmm =)

72. anonymous

good work!

73. anonymous

ok now can u help me with 60%

74. anonymous

ok sure, and it's important you learn the other side of fractions, reduction

75. anonymous

meaning you start with a big fraction, and then reduce it to equivalent fractions (make the numbers smaller)

76. anonymous

so 75% - we said a basic definition of that is 75/100

77. anonymous

as in if 75% of people like football, 75/100 people like football

78. anonymous

so what is 60%?

79. anonymous

3/5 is 60%

80. anonymous

that is definitely true =)

81. anonymous

ok so let's do this systematically

82. anonymous

65% is the same thing as .65

83. anonymous

sorry lol

84. anonymous

60% is the same thing as .6

85. anonymous

which is the same thing as .6/1

86. anonymous

ok but that's not even numbers

87. anonymous

but remember what we can do to fractions to get equivalent fractions

88. anonymous

multiply by 1

89. anonymous

so in this case, we want to get rid of the decimal place

90. anonymous

since fractions don't have decimals (in this context)

91. anonymous

so let's multiple by 10/10

92. anonymous

ok

93. anonymous

which will move each decimal point by one place (since it's one zero in 10)

94. anonymous

you know i owe you big time for this

95. anonymous

it's ok! I've been there, just learned this last year

96. anonymous

so .6/1 x 10/10 = (.6 x 10)/ (1 x 10)

97. anonymous

so we know that 60% - which is the same thing as .6 , actually equals 6/10

98. anonymous

what year of high school are you in i just started junior year

99. anonymous

you can use that system to turn *any* % into a fraction

100. anonymous

I'm a Sr.!

101. anonymous

awesome

102. anonymous

basically multiple by some power of 10, to get rid of the decimals, and you have the equivalent fraction

103. anonymous

so .6/1 x 10/10 = 6/10

104. anonymous

so we know that 6/10 is one equivalent fraction to .6

105. anonymous

if you put it in the calculator, you will see that it's true

106. anonymous

so now that you know 60% is 6/10, you can use the same system (multiplying by 1), to get five equivalent fractions

107. anonymous

108. anonymous

so as a side note before returning to the question, here are a few more examples:

109. anonymous

63% = .63/1 . well, we would need to multiple by 100/100 just so .63 doesn't have a decimal

110. anonymous

so .63/1 x 100/100 = 63/100

111. anonymous

so now you know that 63% is also .63, but also the fraction 63/100

112. anonymous

anyway so back to the question: you now know that 60% = 6/10

113. anonymous

OMG it my curfiew gotta go lets start a session tomorrow around 5:00!!!!!!!!!

114. anonymous

ok =) I'll be around here probably 5 or 6. what timezone lol?
