OpenStudy (koalagurl1):

For question 1, what do you think the answer is?

OpenStudy (mathmale):

Important: apply what you know about algebra. In the first problem, let d represent the number of DVDs owned by Jordan; let s repr. the number owned by Joseph. Who owns the greater number of DVDs? Write one or more formulas to determine how many DVDs Joseph owns.

OpenStudy (koalagurl1):

Nevermind. I'm sure @mathmale will explain better than I can. :|

OpenStudy (scienceteen8):

@KoalaGurl1 i think 1/70 im not good in math

OpenStudy (koalagurl1):

1/70? How did you come up with that?

OpenStudy (mathmale):

Again I ask youi an important question: WHO owns more DVDs? Please, stick to the question at hand...no side conversations, please.

OpenStudy (koalagurl1):

Can you explain? I'm not saying it's wrong...

OpenStudy (scienceteen8):

4/5 divided by 56/1 lol told ya

OpenStudy (mathmale):

Which boy owns more DVDs?

OpenStudy (koalagurl1):

Hang on

OpenStudy (koalagurl1):

I don't think it's a fraction...

OpenStudy (mathmale):

Which boy has more DVDs than the other boy? You don't need numbers here.

OpenStudy (scienceteen8):

mathmale i dont know im not good in fractions at all. but i guess i have to chose so i thought it was the joseph

OpenStudy (mathmale):

I didn't ask you to worry about fractions; I just asked you to read the question and determine from the wording which boy owns more DVDs than the other.

OpenStudy (scienceteen8):

ok an i said i think it is joseph :)

OpenStudy (koalagurl1):

What do you think the answer is now that you know that it is not a fraction?

OpenStudy (mathmale):

That's right. So, Jordan owns fewer DVDs. The very first sentence says that Jordan owns (4/5)th as many DVDs as does Joseph. How would you determine the actual number of DVDs owned by Jordan?

OpenStudy (scienceteen8):

71? @KoalaGurl1

OpenStudy (koalagurl1):

Close, but from my calculations I don't think that's correct.

OpenStudy (mathmale):

How did you get 71?

OpenStudy (scienceteen8):

i divided 56 4/5 and 4/5

OpenStudy (koalagurl1):

Try dividing 56 by 4.

OpenStudy (scienceteen8):

ok

OpenStudy (koalagurl1):

What did you get?

OpenStudy (scienceteen8):

14

OpenStudy (koalagurl1):

Ok, good. That's correct.

OpenStudy (scienceteen8):

ok

OpenStudy (koalagurl1):

Now, add 14 to 56.

OpenStudy (scienceteen8):

70

OpenStudy (koalagurl1):

Yep, that's it!

OpenStudy (scienceteen8):

ok lol :) :D

OpenStudy (koalagurl1):

Great job! :)

OpenStudy (scienceteen8):

thnx lol ok now what about num 2 lol

OpenStudy (koalagurl1):

I'm looking at it right now. Hang on one second. :)

OpenStudy (scienceteen8):

ok

OpenStudy (koalagurl1):

Ok, who has more plants?

OpenStudy (mathmale):

Which girl owns more plants? (See, KoalaGurl1 and I think alike!)

OpenStudy (scienceteen8):

i think elizabith

OpenStudy (koalagurl1):

Haha, sorry @mathmale I kinda stole it from you :P

OpenStudy (scienceteen8):

lol

OpenStudy (koalagurl1):

And, yes

OpenStudy (mathmale):

What would it take to make your feel sure? No, I'm letting you, K. G., continue, since scienceteen has asked for you. Lucky you.

OpenStudy (koalagurl1):

Ok, that was correct. Now, turn 1 7/10 into an improper fraction.

OpenStudy (scienceteen8):

it is......17/10? lol

OpenStudy (koalagurl1):

Yep, good job!

OpenStudy (scienceteen8):

woo hoo lol :)

OpenStudy (koalagurl1):

Now, divide 51 by 17.

OpenStudy (scienceteen8):

how did u get 51? an i think its 14

OpenStudy (koalagurl1):

Elizabeth has 51 plants.

OpenStudy (scienceteen8):

oh duh lol idk why i did not see that lol

OpenStudy (koalagurl1):

It's ok! Don't worry. :)

OpenStudy (scienceteen8):

lol is that all or is there more to it?

OpenStudy (koalagurl1):

What did you get?

OpenStudy (koalagurl1):

When you divided 51 by 17.

OpenStudy (scienceteen8):

14 lol

OpenStudy (koalagurl1):

How did you get that?

OpenStudy (scienceteen8):

i ment 3 i ment to send 14 to someone else lol

OpenStudy (koalagurl1):

Oh ok.

OpenStudy (koalagurl1):

What is 3x7?

OpenStudy (scienceteen8):

21

OpenStudy (koalagurl1):

Yep, now take 21 away from 51.

OpenStudy (scienceteen8):

-30

OpenStudy (koalagurl1):

Nope... Just 30. No minus.

OpenStudy (scienceteen8):

ok lol

OpenStudy (koalagurl1):

And that's your answer.

OpenStudy (scienceteen8):

ok thank you so much :) now for a good laugh do you want to see what my sister sent me and her ipod has auto correct so it changed the words but i will tell u the real words if u wana hear it
