## anonymous one year ago A recipe calls for cups of flour, ￼ cup of white sugar, and ￼ cup of brown sugar. The recipe makes 6 servings. (a) How many cups of flour are there per serving? Show your work. (b) How many total cups of sugar (white and brown) are there per serving? Show your work. (c) Suppose you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe? Show your work

the fractions are not showing up what does it say there

thats what i see, fix that

A recipe calls for cups 1 1/3 of flour, ￼1/2 cup of white sugar, and 2/3 ￼ cup of brown sugar. The recipe makes 6 servings. (a) How many cups of flour are there per serving? Show your work. (b) How many total cups of sugar (white and brown) are there per serving? Show your work. (c) Suppose you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe? Show your work

10. dan815

now u see all these make 6 servings

11. dan815

so if u use 1/6th of all this you get the ammount for 1 serving

12. anonymous

yes I do

13. anonymous

Okay.

14. dan815

does that make sense?

15. anonymous

So the answer would be 1/6 Correct? for (a)

16. dan815

no lol what!?!

17. dan815

okay look at this other question

18. dan815

suppose I pay 2 dollars for 10 jelly beans

19. dan815

what does that mean 5 jelly beans cost

20. anonymous

1 dollar

21. dan815

right, what does that mean 1 jelly bean costs :P

22. dan815

you see in your mind you were able to do this split very intuitively

23. dan815

|dw:1435577369110:dw|

24. dan815

you saw the 10 was split in half so u split the 2 in half too

25. anonymous

So we have to Add All the Fractions Together? Correct?

26. dan815

wait answer this question first, how much is 1 jelly bean?

27. dan815

I split the 10 beans into 10 parts to get 1 bean

28. dan815

so you have to split the only into 10 parts too, and see how much is in each part, this is known as divisiion

29. anonymous

0.4

30. dan815

not quite

31. dan815

10 was split into 10 parts to get 1 in each part 2 dollars split into 10 parts to get ___ in each part?

32. anonymous

Sorry to be rude But im Kinda in a Hurry could we speed this up xD

33. dan815

im trying to go as fast as possible here

34. dan815

The faster you understand the faster we can move on

35. anonymous

2/5 = 0.4 :P I did 2 divided by 5

36. dan815

its 2/10

37. dan815

2 = 10 jelly beans 2/10 = 10/10 jelly beans 0.2 = 1 jelly bean

38. anonymous

What Should I divided im trying to Understand but i Just dont get it with The Fractions part

39. dan815

same thing with the fractions

40. anonymous

Okay so the Anwser is 0.2/0.20

41. dan815

|dw:1435577709925:dw|

42. anonymous

Okay Add all fractions then Divide it By 6 Correct :D for Q.A

43. dan815

ahh maybe you should work on this when you have time,

44. anonymous

Lets do B.

45. anonymous

Im trying to understand this :O

46. anonymous

@dan815 I think I got it after reviewing it :D

47. perl

*

48. anonymous

Halp anyone Im begging you :(

49. perl

Do you mind me starting over?

50. anonymous

Yes

51. anonymous

I got (a).0.2 (b0 1 1/6

52. anonymous

(a). 0.2 (b). 1 1/6 (c).3 1/2

53. perl

A recipe calls for cups 1 1/3 or 4/3 cups of flour, ￼1/2 cup of white sugar, and 2/3 ￼ cup of brown sugar. The recipe makes 6 servings. (a) How many cups of flour are there per serving? Show your work. $\Large \rm \frac{4/3 ~ cups }{6~serving} = \frac{x~ cups}{1~serving}$$$\Large x = \frac 2 9 ~ \rm cups$$

54. anonymous

So (a). 2/9 is that Correct :D

55. perl

Does that make sense how I got that, I made a proportion. and solve for x, cross multiply

56. anonymous

Yes Exact Sense Thanks So much :D

57. anonymous

Was I correct with B?

58. perl

A recipe calls for 4/3 cups of flour, ￼1/2 cup of white sugar, and 2/3 ￼ cup of brown sugar. The recipe makes 6 servings. (b) How many total cups of sugar (white and brown) are there per serving? Show your work. $\Large \rm \frac{1/2 + 2/3 ~ cups ~ sugar }{6~servings} = \frac{x~ cups~sugar}{1~serving}$$\Large x = \frac {7}{36} ~ \rm cups~ sugar$

59. anonymous

THX U R THE BEST! ( Sorry it to song long I was trying to figure out how to understand :P)

60. anonymous

So*

61. anonymous

Okay

62. anonymous

Do I add or times The White Sugar and Brown Sugar then X's it by 3?

63. perl

We can think about it logically. If the directions asked for 12 servings, that means we would double each part of the recipe. or multiply by 2. But the directions say to get 9 servings, that is not exactly double. Instead it is the factor 9/6 multiply each component of the recipe by 9/6

64. anonymous

So WS x 9/6 and BS x 9/6 Correct?

65. perl

yes

66. perl

Assuming ws you mean white sugar.

67. anonymous

Once I get the Anwser for Both do I add them together?

68. anonymous

@perl Do i?

69. perl

We only need to find the additional amount of flour needed for 9 servings. Therefore multiply 9/6 by the flour amount for 6 servings. I may have misread the question.

70. anonymous

Okay so WS =3/4 BS= (1)

71. anonymous

WS + BS = 1 1/6

72. anonymous

Subtract what??

73. anonymous

3/5

74. perl

Let's do it in steps.

75. anonymous

Yes

76. perl

Let's post all the given info again A recipe calls for cups 4/3 of flour, ￼1/2 cup of white sugar, and 2/3 ￼ cup of brown sugar. The recipe makes 6 servings. Question Part c) (c) Suppose you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe? The question is only asking about the additional flour needed to make 9 servings, not the sugar.

77. anonymous

So, How do we get 9 servings :P I might be wrong

78. perl

we can multiply 9/6 by the old flour amount to get the new amount of flour needed for 9 servings

79. perl

you know what, let's use a proportion since that made sense earlier

80. anonymous

9/6 x 4/3?

81. perl

$$\Large \frac{4/3 \rm~ cup ~flour}{6 ~\rm servings} = \frac{x \rm ~ cup ~flour}{9 ~ \rm servings}$$

82. perl

when we cross multiply we get 9 /6 * 4/3 = x

83. perl

Agreed?

84. anonymous

Okay My keyboard got disconnected sorry :P

85. perl

So we are very close to finishing this. The only catch here is , the question asks for the additional amount of flour.

86. anonymous

= 2? correct

87. perl

The total amount of flour needed for 9 servings is 9/6 * 4/3 . We already have 4/3 cups. What is the additional amount. Hint, subtract

88. anonymous

0.6

89. perl

the question asks how much more flour. 0.6 is close, but lets make it exact

90. perl

The exact decimal is 0.666666... what nice fraction is this?

91. anonymous

3/5

92. perl

close , 2/3

93. perl

there are more decimals in 2/3

94. anonymous

Okay so C is 2/3

95. perl

you got it

96. anonymous

oKay a few more

97. perl

Can you post a new question?

98. anonymous

Emmanuel bought 40 lb of potting soil this week. This amount is 4 lb more than three times the amount of potting soil he bought last week. Answer the following questions to find the number of pounds of soil Emmanuel purchased last week. (a) What is the unknown information? (b) Let p represent the unknown information. Write an equation to model the problem. (c) Which number 10, 11, or 12 will solve the equation in Part B? Show your work. (d) How many pounds of potting soil did Emmanuel buy last week?

99. perl

In case I get disconnected.

100. anonymous

Hello Anyone there

101. perl

Which part do you have difficulty with?

102. anonymous

these questions then we are done :P

103. perl

Emmanuel bought 40 lb of potting soil this week. This amount is 4 lb more than three times the amount of potting soil he bought last week. Answer the following questions to find the number of pounds of soil Emmanuel purchased last week. (a) What is the unknown information? hint : Do we know what Emmanuel purchased last week?

104. anonymous

Yeswe do

105. perl

Please show me where that is given :)

106. anonymous

Emmanuel bought 40 lb of potting soil this week

107. perl

That is the amount for this week, not last week.

108. perl

Do we know how much he bought last week? if we don't know, that is the 'unknown'

109. anonymous

Unknowkn = x

110. perl

The question asks what is the unknown information. Can you be more specific about what x represents?

111. perl

in the context of this problem

112. anonymous

Okay Not getting

113. perl

Let's go over the directions again . Read it carefully Emmanuel bought 40 lb of potting soil this week. This amount is 4 lb more than three times the amount of potting soil he bought last week.  a) What is the unknown information? Do we know how much soil he bought this week? yes Do we know how much soil he bought last week? no

114. anonymous

Okay so the Anwser is...

115. perl

I can only guide you, I can't give you the direct answer.
