  • dan815
now u see all these make 6 servings
dan815
  • dan815
so if u use 1/6th of all this you get the ammount for 1 serving
anonymous
  • anonymous
yes I do
anonymous
  • anonymous
Okay.
dan815
  • dan815
does that make sense?
anonymous
  • anonymous
So the answer would be 1/6 Correct? for (a)

no lol what!?!

okay look at this other question

suppose I pay 2 dollars for 10 jelly beans
dan815
  • dan815
what does that mean 5 jelly beans cost
anonymous
  • anonymous
1 dollar
dan815
  • dan815
right, what does that mean 1 jelly bean costs :P
dan815
  • dan815
you see in your mind you were able to do this split very intuitively
dan815
  • dan815
|dw:1435577369110:dw|
dan815
  • dan815
you saw the 10 was split in half so u split the 2 in half too
anonymous
  • anonymous
So we have to Add All the Fractions Together? Correct?
dan815
  • dan815
wait answer this question first, how much is 1 jelly bean?
dan815
  • dan815
I split the 10 beans into 10 parts to get 1 bean
dan815
  • 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
anonymous
  • anonymous
0.4

not quite

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

2/5 = 0.4 :P I did 2 divided by 5
dan815
  • dan815
its 2/10
dan815
  • dan815
2 = 10 jelly beans 2/10 = 10/10 jelly beans 0.2 = 1 jelly bean

What Should I divided im trying to Understand but i Just dont get it with The Fractions part
dan815
  • dan815
same thing with the fractions

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. \[ \Large \rm \frac{4/3 ~ cups }{6~serving} = \frac{x~ cups}{1~serving}\]$$ \Large x = \frac 2 9 ~ \rm cups$$
anonymous

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

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

Yes Exact Sense Thanks So much :D

anonymous

Okay

  • anonymous
Do I add or times The White Sugar and Brown Sugar then X's it by 3?
perl
  • 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
anonymous
  • anonymous
So WS x 9/6 and BS x 9/6 Correct?
perl
  • perl
yes
perl
  • perl
Assuming ws you mean white sugar.
anonymous
  • anonymous
Once I get the Anwser for Both do I add them together?
anonymous
  • anonymous
@perl Do i?
perl
  • 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.
anonymous
  • anonymous
Okay so WS =3/4 BS= (1)
anonymous
  • anonymous
WS + BS = 1 1/6
anonymous
  • anonymous
Subtract what??
anonymous
  • anonymous
3/5
perl
  • perl
Let's do it in steps.
anonymous
  • anonymous
Yes
perl
  • 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.
anonymous
  • anonymous
So, How do we get 9 servings :P I might be wrong
perl
  • perl
we can multiply 9/6 by the old flour amount to get the new amount of flour needed for 9 servings
perl
  • perl
you know what, let's use a proportion since that made sense earlier
anonymous
  • anonymous
9/6 x 4/3?
perl
  • perl
$$ \Large \frac{4/3 \rm~ cup ~flour}{6 ~\rm servings} = \frac{x \rm ~ cup ~flour}{9 ~ \rm servings} $$
perl
  • perl
when we cross multiply we get 9 /6 * 4/3 = x
perl
  • perl
Agreed?
anonymous
  • anonymous
Okay My keyboard got disconnected sorry :P
perl
  • perl
So we are very close to finishing this. The only catch here is , the question asks for the additional amount of flour.
anonymous
  • anonymous
= 2? correct
perl
  • 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
anonymous
  • anonymous
0.6
perl
  • perl
the question asks how much more flour. 0.6 is close, but lets make it exact
perl
  • perl
The exact decimal is 0.666666... what nice fraction is this?
anonymous
  • anonymous
3/5
perl
  • perl
close , 2/3
perl
  • perl
there are more decimals in 2/3
anonymous
  • anonymous
Okay so C is 2/3

you got it

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