OpenStudy (benlindquist):

what would you change these into

OpenStudy (igreen):

I believe you're incorrect.

OpenStudy (anonymous):

1/3

OpenStudy (igreen):

Change 33 1/3% into a decimal, what do you get?

OpenStudy (igreen):

@Juliusmattos12 Please no answers.

OpenStudy (anonymous):

-,-

OpenStudy (benlindquist):

yes, I'm trying to fix it

OpenStudy (benlindquist):

1/3

OpenStudy (igreen):

Correct.

OpenStudy (igreen):

33 1/3% is equal to 1/3

OpenStudy (igreen):

Can you express 1/3 as a decimal?

OpenStudy (anonymous):

so I was right xD

OpenStudy (igreen):

@Juliusmattos12 No, we're not looking for things that are the same, it's asking for values that are different.

OpenStudy (benlindquist):

|dw:1452178366562:dw|

OpenStudy (benlindquist):

.3

OpenStudy (igreen):

Since 33 1/3% and 1/3 are equal, they are not our answers.

OpenStudy (igreen):

Yes, you're correct! So 33 1/3%, 1/3, and \(\sf 0.\overline 3\) are all equal, that leaves one option left

OpenStudy (benlindquist):

ok

OpenStudy (mathmale):

Wait, please. three of the possible answers are alike in a particular way, whereas one is not. Which one does not have the pattern of the other three?

OpenStudy (anonymous):

WHAT Y WAS I TOLD AS AN ABUSE

OpenStudy (benlindquist):

1/3 is different

OpenStudy (mathmale):

Why is 1/3 different?

OpenStudy (igreen):

@benlindquist The question is asking for one of the answers that are DIFFERENT from the rest. You said \(\sf 33 \dfrac{1}{3} \%\) is equal to \(\sf\dfrac{1}{3}\), and that \(\sf\dfrac{1}{3} = 0.\overline 3\).

OpenStudy (mathmale):

"You said" does not necessarily mean that what was said is correct. Think again.

OpenStudy (benlindquist):

the last one would be .333

OpenStudy (mathmale):

what do you mean? Unclear.

OpenStudy (igreen):

^ I'm thinking the same of your previous statement.

OpenStudy (igreen):

I believe I don't see anything wrong with what was said before.

OpenStudy (mathmale):

So, which of the four possible answers does not fit in with the other three? Why?

OpenStudy (benlindquist):

33.3 I'm seeing what is wrong

OpenStudy (mathmale):

What's wrong with 33.3?

OpenStudy (benlindquist):

its would be 0.333 and not 0.3

OpenStudy (mathmale):

Ben: Try this: Change the first possible answer into a decimal fraction. Now multiply all four possible answers by 100. Your results don't have to be exact. What do you get? Does this help you answer the original quation?

OpenStudy (benlindquist):

1. 0.3

OpenStudy (benlindquist):

2.30

OpenStudy (benlindquist):

3.33

OpenStudy (benlindquist):

4.3330

OpenStudy (mathmale):

The first possible answer is 33 1/3%. This can be converted into the decimal fraction .3333.... Multiply this result by 100. What is an approx. result (product)?

OpenStudy (benlindquist):

33.33

OpenStudy (benlindquist):

so the 2nd problem would be the different one

OpenStudy (mathmale):

Yes, you get approx 33.33 from the first possible answer. Next, multiply the next one, 0.3 with a bar over the 3, by 100. Approx answer?

OpenStudy (benlindquist):

30

OpenStudy (mathmale):

Please move on to the third possible answer. Mult 1/3 by 100.

OpenStudy (benlindquist):

33.33 with a bar over since it repeats itself

OpenStudy (mathmale):

good. Now mult. the fourth possible answer by 100.

OpenStudy (benlindquist):

3330

OpenStudy (mathmale):

Your four results are 33.33, 30, 33.33, 3330. Which one does not fit in with the others?

OpenStudy (benlindquist):

30

OpenStudy (mathmale):

Are you saying that 3330 fits the pattern better than do 33.33, 30 and 33.33?

OpenStudy (mathmale):

I am going to have you line up out in front of y our house with three of your cousins standing next to you. I'm going to give one of your cousins $3000. I'm giving $30 to you and to each of your other two cousins. Fair?

OpenStudy (benlindquist):

no

OpenStudy (mathmale):

Why not? I'm always fair.

OpenStudy (benlindquist):

is it because of the decimal?

OpenStudy (mathmale):

No. Which one does not fit in with the others? 30, 33, 33, 3000

OpenStudy (benlindquist):

It should be the last one?

OpenStudy (mathmale):

right. very good.

OpenStudy (mathmale):

Thx for your patience and for sticking with this discussion.

OpenStudy (benlindquist):

thank you @mathmale

OpenStudy (mathmale):

My great pleasure.
