I know. You cannot help me with a whole work sheet. Sorry.

I'll delete.

4. Mertsj

Well let's talk about the first one. If 8 quarts costs $5.44 how would you find the cost of 1 quart? 5. help123please. Oh, ok. U do 5.44/8 6. help123please. 0.68? 7. Mertsj |dw:1359427317441:dw| 8. Mertsj yep. .68 9. help123please. Do you know how to do the chart? 10. Mertsj For the skittles...if 20 ounces cost 3.79 how much does 1 ounce cost. I think you do the chart by filling it in for the various products. 11. help123please. Um. I got a really long decimal for that one. 12. help123please. 0.1825 13. Mertsj It says you can complete the chart OR use a proportion. 14. Mertsj That would be 18 1/4 cents per ounce 15. help123please. My teacher said she wanted both, but okay :) 16. help123please. 18 1/4? mk 17. help123please. done. 18. Mertsj I'm not sure what she wants in the chart. Didn't she do an example in class? 19. help123please. no. ;/ Ill ask tomorrow; thats ok. 20. Mertsj ok 21. help123please. we can do the proportion part for now. 22. Mertsj ok. Do you know how to do those? 23. help123please. i think, but for the spring water one i get a long decimal 24. Mertsj Yes. It comes out to be .119166666 I think I would round that to$.12 per bottle

oh,ok,tnx

26. Mertsj

yw

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

:0 99 smart score :0

29. Mertsj

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

.239583333 rounds to how many cents per card?

um.. .20?

35. Mertsj

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

36. Mertsj

.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

Yes, for the valentine cards.

oh, ok

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

i mean dollars

43. Mertsj

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

47. Mertsj

then put .24

oh. zero dollars and 24 cents.ok

49. Mertsj

yes

I wrote it. Thanks.

51. Mertsj

yw

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

53. Mertsj

That was the correct equation for the rose.

great! let me work it out.

2.49, yes?

56. Mertsj

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

yes sir.

58. Mertsj

Is 2.499 closer to 2.49 or 2.50?

2.50

60. Mertsj

Then you should put 2.50 per rose

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

62. Mertsj

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

ok

let me attempt it.

68. Mertsj

Yes, the hangers. ok

so, A is .12.

70. Mertsj

yes

B is 0.149.

72. Mertsj

yes

C is .1325

So Id guess A is the better buy?

75. Mertsj

Clearly

ok. 1 sec

done

78. Mertsj

Good. Which is the better vitamin buy?

let me see.

one minute.

almost done

A is 0.03

83. Mertsj

yes

B is 0.0299

85. Mertsj

Yes. Which is a tiny bit cheaper than A

Really?

I would've thought A was the cheapest.

88. Mertsj

.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

Yes. Very good.

thank you,sir

now,the next problem...ummm

Hmmm

97. Mertsj

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

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

Hm.... One minute,

3/4 of an hr

102. Mertsj

Very good.

And 3/4 is 0.75

104. Mertsj

yes

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

?

107. 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.

108. Mertsj

And it's 225 miles NOT 2.25

oh, yes, typo, i apologize.

110. Mertsj

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

60 miles per hr?

112. Mertsj

yes

great, tnx

now the map.

115. Mertsj

yes

116. Mertsj

centimeters PER mile

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

118. Mertsj

The word after PER goes on the bottom

oh ok. sorry, i get those mixed up/

120. Mertsj

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

1.3 cm per one mile?

122. 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.

Oh,alright. Will do.

one moment.

mk. now the other one.

it says to fill in the table.

127. Mertsj

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

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

let me try it really quick

hm...

132. Mertsj

56 miles per 2 gallons

he gets 56 miles per gallpm

134. Mertsj

No. He gets 56 miles on 2 gallons

oops. yes. i did 168-224

got 56

137. 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?

so, 56,112,168,224,280,356

?

140. Mertsj

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

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

Or no?

143. Mertsj

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

144. Mertsj

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