Mertsj Group Title |dw:1359427317441:dw| 8. Mertsj Group Title yep. .68 9. help123please. Group Title Do you know how to do the chart? 10. Mertsj Group Title 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. 11. help123please. Group Title Um. I got a really long decimal for that one. 12. help123please. Group Title 0.1825 13. Mertsj Group Title It says you can complete the chart OR use a proportion. 14. Mertsj Group Title That would be 18 1/4 cents per ounce 15. help123please. Group Title My teacher said she wanted both, but okay :) 16. help123please. Group Title 18 1/4? mk 17. help123please.

Mertsj Group Title ok 21. help123please. Group Title we can do the proportion part for now. 22. Mertsj Group Title ok. Do you know how to do those? 23. help123please. Group Title i think, but for the spring water one i get a long decimal 24. Mertsj Group Title Yes. It comes out to be .119166666 I think I would round that to$.12 per bottle

oh,ok,tnx

26. Mertsj Group Title

yw

wanna help with the others? u don't have to if u don't want to

:0 99 smart score :0

29. Mertsj Group Title

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?

33. Mertsj Group Title

.239583333 rounds to how many cents per card?

um.. .20?

35. Mertsj Group Title

When it say per card or per bottle or per rose you know that goes on the bottom.

36. Mertsj Group Title

.239 is more than 23 cents but less than 24 cents but it is closer to 24 cents.

oh; so $\frac{ 5.75 }{ 24 }$

?

39. Mertsj Group Title

Yes, for the valentine cards.

oh, ok

oh. let me see. so, 23 cents per card,yes?

i mean dollars

43. Mertsj Group Title

.239 is closer to .24 so round to .24 which is $.24 or 24 cents 44. help123please. Group Title $\frac{ 29.99 }{ 12 } = \frac{ ? }{ 1 } ?$ 45. Mertsj Group Title Yes. 46. help123please. Group Title it is asking$ _____________ per card

47. Mertsj Group Title

then put .24

oh. zero dollars and 24 cents.ok

49. Mertsj Group Title

yes

I wrote it. Thanks.

51. Mertsj Group Title

yw

For the second one, can u look at the equation i typed

53. Mertsj Group Title

That was the correct equation for the rose.

great! let me work it out.

2.49, yes?

56. Mertsj Group Title

You seem to have a little trouble with the rounding. Did you get 2.499166666?

yes sir.

58. Mertsj Group Title

Is 2.499 closer to 2.49 or 2.50?

2.50

60. Mertsj Group Title

Then you should put 2.50 per rose

Okay, sorry. I am not the best at math,

62. Mertsj Group Title

Not a problem. You will learn.

thanks for helping me and putting up with me. give me a second to write that down

Okedokey.

65. Mertsj Group Title

ok

let me attempt it.

68. Mertsj Group Title

Yes, the hangers. ok

so, A is .12.

70. Mertsj Group Title

yes

B is 0.149.

72. Mertsj Group Title

yes

C is .1325

So Id guess A is the better buy?

75. Mertsj Group Title

Clearly

ok. 1 sec

done

78. Mertsj Group Title

Good. Which is the better vitamin buy?

let me see.

one minute.

almost done

A is 0.03

83. Mertsj Group Title

yes

B is 0.0299

85. Mertsj Group Title

Yes. Which is a tiny bit cheaper than A

Really?

I would've thought A was the cheapest.

88. Mertsj Group Title

.0299 is less than .0300

nvm no

its 1 dollar b is just cents

And c is....

0.0216, so C is the cheapest

93. Mertsj Group Title

Yes. Very good.

thank you,sir

now,the next problem...ummm

Hmmm

97. Mertsj Group Title

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?

99. Mertsj Group Title

How much of an hour is 15 minutes? (Think of the clock face...)

Hm.... One minute,

3/4 of an hr

102. Mertsj Group Title

Very good.

And 3/4 is 0.75

104. Mertsj Group Title

yes

$\frac{ 0.75 }{ 2.25 } = \frac{ ? }{ 1}$

?

107. Mertsj Group Title

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.

108. Mertsj Group Title

And it's 225 miles NOT 2.25

oh, yes, typo, i apologize.

110. Mertsj Group Title

$\frac{225miles}{3.75 hours}$

60 miles per hr?

112. Mertsj Group Title

yes

great, tnx

now the map.

115. Mertsj Group Title

yes

116. Mertsj Group Title

centimeters PER mile

yes, so $\frac{ miles }{ centimeters}$

118. Mertsj Group Title

The word after PER goes on the bottom

oh ok. sorry, i get those mixed up/

120. Mertsj Group Title

$centimeters per mile = \frac{centimeters}{miles}$

1.3 cm per one mile?

122. Mertsj Group Title

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.

127. Mertsj Group Title

But first it wants to know how many miles PER gallon his car gets.

So, a multiple step problem. shall I attempt it?

129. Mertsj Group Title

Just figure out first how many miles per gallon his car gets.

let me try it really quick

hm...

132. Mertsj Group Title

56 miles per 2 gallons

he gets 56 miles per gallpm

134. Mertsj Group Title

No. He gets 56 miles on 2 gallons

oops. yes. i did 168-224

got 56

137. Mertsj Group Title

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

?

140. Mertsj Group Title

$\frac{56 miles}{2 gallons}=\frac{x miles}{1 gallon}$

so, 56,112,168,224,280,356 Could I fill that in?

Or no?

143. Mertsj Group Title

Based on the table, how many miles per gallon does Rolando's car get?

144. Mertsj Group Title

That is the first question the problem asks. You need to answer it.
