Well let's talk about the first one. If 8 quarts costs $5.44 how would you find the cost of 1 quart?
anonymous
  • anonymous
Oh, ok. U do 5.44/8
anonymous
  • anonymous
0.68?
Mertsj
  • Mertsj
|dw:1359427317441:dw|
Mertsj
  • Mertsj
yep. .68
anonymous
  • anonymous
Do you know how to do the chart?
Mertsj
  • Mertsj
For the skittles...if 20 ounces cost 3.79 how much does 1 ounce cost. I think you do the chart by filling it in for the various products.
anonymous
  • anonymous
Um. I got a really long decimal for that one.
anonymous
  • anonymous
0.1825
Mertsj
  • Mertsj
It says you can complete the chart OR use a proportion.
Mertsj
  • Mertsj
That would be 18 1/4 cents per ounce
anonymous
  • anonymous
My teacher said she wanted both, but okay :)
anonymous
  • anonymous
18 1/4? mk
anonymous
  • anonymous
done.
Mertsj
  • Mertsj
I'm not sure what she wants in the chart. Didn't she do an example in class?
anonymous
  • anonymous
no. ;/ Ill ask tomorrow; thats ok.
Mertsj
  • Mertsj
ok
anonymous
  • anonymous
we can do the proportion part for now.
Mertsj
  • Mertsj
ok. Do you know how to do those?
anonymous
  • anonymous
i think, but for the spring water one i get a long decimal
Mertsj
  • Mertsj
Yes. It comes out to be .119166666 I think I would round that to $.12 per bottle
anonymous
  • anonymous
oh,ok,tnx
Mertsj
  • Mertsj
yw
anonymous
  • anonymous
wanna help with the others? u don't have to if u don't want to
anonymous
  • anonymous
:0 99 smart score :0
Mertsj
  • Mertsj
I can check your answers if you want.
anonymous
  • anonymous
mk. let me work them out really quick
anonymous
  • anonymous
hmm. i get a long decimal both ways.
anonymous
  • anonymous
how do you decide what goes on the numerator/denominator?
Mertsj
  • Mertsj
.239583333 rounds to how many cents per card?
anonymous
  • anonymous
um.. .20?
Mertsj
  • Mertsj
When it say per card or per bottle or per rose you know that goes on the bottom.
Mertsj
  • Mertsj
.239 is more than 23 cents but less than 24 cents but it is closer to 24 cents.
anonymous
  • anonymous
oh; so \[\frac{ 5.75 }{ 24 }\]
anonymous
  • anonymous
?
Mertsj
  • Mertsj
Yes, for the valentine cards.
anonymous
  • anonymous
oh, ok
anonymous
  • anonymous
oh. let me see. so, 23 cents per card,yes?
anonymous
  • anonymous
i mean dollars
Mertsj
  • Mertsj
.239 is closer to .24 so round to .24 which is $.24 or 24 cents
anonymous
  • anonymous
\[\frac{ 29.99 }{ 12 } = \frac{ ? }{ 1 } ?\]
Mertsj
  • Mertsj
Yes.
anonymous
  • anonymous
it is asking $ _____________ per card
Mertsj
  • Mertsj
then put .24
anonymous
  • anonymous
oh. zero dollars and 24 cents.ok
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
I wrote it. Thanks.
Mertsj
  • Mertsj
yw
anonymous
  • anonymous
For the second one, can u look at the equation i typed
Mertsj
  • Mertsj
That was the correct equation for the rose.
anonymous
  • anonymous
great! let me work it out.
anonymous
  • anonymous
2.49, yes?
Mertsj
  • Mertsj
You seem to have a little trouble with the rounding. Did you get 2.499166666?
anonymous
  • anonymous
yes sir.
Mertsj
  • Mertsj
Is 2.499 closer to 2.49 or 2.50?
anonymous
  • anonymous
2.50
Mertsj
  • Mertsj
Then you should put 2.50 per rose
anonymous
  • anonymous
Okay, sorry. I am not the best at math,
Mertsj
  • Mertsj
Not a problem. You will learn.
anonymous
  • anonymous
thanks for helping me and putting up with me. give me a second to write that down
anonymous
  • anonymous
Okedokey.
Mertsj
  • Mertsj
ok
anonymous
  • anonymous
next is the better buy.
anonymous
  • anonymous
let me attempt it.
Mertsj
  • Mertsj
Yes, the hangers. ok
anonymous
  • anonymous
so, A is .12.
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
B is 0.149.
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
C is .1325
anonymous
  • anonymous
So Id guess A is the better buy?
Mertsj
  • Mertsj
Clearly
anonymous
  • anonymous
ok. 1 sec
anonymous
  • anonymous
done
Mertsj
  • Mertsj
Good. Which is the better vitamin buy?
anonymous
  • anonymous
let me see.
anonymous
  • anonymous
one minute.
anonymous
  • anonymous
almost done
anonymous
  • anonymous
A is 0.03
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
B is 0.0299
Mertsj
  • Mertsj
Yes. Which is a tiny bit cheaper than A
anonymous
  • anonymous
Really?
anonymous
  • anonymous
I would've thought A was the cheapest.
Mertsj
  • Mertsj
.0299 is less than .0300
anonymous
  • anonymous
nvm no
anonymous
  • anonymous
its 1 dollar b is just cents
anonymous
  • anonymous
And c is....
anonymous
  • anonymous
0.0216, so C is the cheapest
Mertsj
  • Mertsj
Yes. Very good.
anonymous
  • anonymous
thank you,sir
anonymous
  • anonymous
now,the next problem...ummm
anonymous
  • anonymous
Hmmm
Mertsj
  • Mertsj
Yes. It gives you the time in hours and minutes and then it asks for miles per hour.
anonymous
  • anonymous
How much is 45 mins of an hour?
Mertsj
  • Mertsj
How much of an hour is 15 minutes? (Think of the clock face...)
anonymous
  • anonymous
Hm.... One minute,
anonymous
  • anonymous
3/4 of an hr
Mertsj
  • Mertsj
Very good.
anonymous
  • anonymous
And 3/4 is 0.75
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
\[\frac{ 0.75 }{ 2.25 } = \frac{ ? }{ 1}\]
anonymous
  • anonymous
?
Mertsj
  • Mertsj
Just a minute 3 hours and 45 minutes is 3.75 hours and you are trying to find miles per hour so hours should go on the bottom.
Mertsj
  • Mertsj
And it's 225 miles NOT 2.25
anonymous
  • anonymous
oh, yes, typo, i apologize.
Mertsj
  • Mertsj
\[\frac{225miles}{3.75 hours}\]
anonymous
  • anonymous
60 miles per hr?
Mertsj
  • Mertsj
yes
anonymous
  • anonymous
great, tnx
anonymous
  • anonymous
now the map.
Mertsj
  • Mertsj
yes
Mertsj
  • Mertsj
centimeters PER mile
anonymous
  • anonymous
yes, so \[\frac{ miles }{ centimeters}\]
Mertsj
  • Mertsj
The word after PER goes on the bottom
anonymous
  • anonymous
oh ok. sorry, i get those mixed up/
Mertsj
  • Mertsj
\[centimeters per mile = \frac{centimeters}{miles}\]
anonymous
  • anonymous
1.3 cm per one mile?
Mertsj
  • Mertsj
Yes. Actually it is 1.333 which is 1 and 1/3. She might want the exact answer this time. You could put both perhaps.
anonymous
  • anonymous
Oh,alright. Will do.
anonymous
  • anonymous
one moment.
anonymous
  • anonymous
mk. now the other one.
anonymous
  • anonymous
it says to fill in the table.
Mertsj
  • Mertsj
But first it wants to know how many miles PER gallon his car gets.
anonymous
  • anonymous
So, a multiple step problem. shall I attempt it?
Mertsj
  • Mertsj
Just figure out first how many miles per gallon his car gets.
anonymous
  • anonymous
let me try it really quick
anonymous
  • anonymous
hm...
Mertsj
  • Mertsj
56 miles per 2 gallons
anonymous
  • anonymous
he gets 56 miles per gallpm
Mertsj
  • Mertsj
No. He gets 56 miles on 2 gallons
anonymous
  • anonymous
oops. yes. i did 168-224
anonymous
  • anonymous
got 56
Mertsj
  • Mertsj
Look at the first column of the table. It tells you that he goes 56 miles on 2 gallons of gas. How far would he go on 1 gallon of gas?
anonymous
  • anonymous
so, 56,112,168,224,280,356
anonymous
  • anonymous
?
Mertsj
  • Mertsj
\[\frac{56 miles}{2 gallons}=\frac{x miles}{1 gallon}\]
anonymous
  • anonymous
so, 56,112,168,224,280,356 Could I fill that in?
anonymous
  • anonymous
Or no?
Mertsj
  • Mertsj
Based on the table, how many miles per gallon does Rolando's car get?
Mertsj
  • Mertsj
That is the first question the problem asks. You need to answer it.
