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