Ms.Sue both questions were wrong they both were not A.
Like fractions are "different fractions with the same denominator".
So, with that, the answers for these two are both B as the correct answer. I hope this helps! :)
I don't even know what r like fractions. type it up on google girl lol
Sorry. I was thinking of equivalent fractions.
Like fractions have the same denominator.

You're welcome, Sarah. :)
P.S. the sentence with the quotations above are from the website Ms. Sue provided. Except, I went to the site before she even posted it on here.
3. B is correct.
Actually, it is C, I read is kind of wrong.
It would be C because 19.872 can't be rounded up to 19.88. It can only stay 19.87. Sorry for my error.

I'm not so sure about this one?
For 3 it says round to the nearest hundredth wouldn't it be B?
All of your answers are right.
10)
4/13 = 0.30769 = 0.308
3. 7.2 x 12 x 0.23 = ? Round to the nearest hundredth.
19.872
since 2 is less than five, the nearest hundredth is 7
so
19.87
which is C as Brady said.
4. Correct
5. Correct
6. Correct
7. Correct
8. I think it's D, but all of the others seem to be repeating as well.
9. Correct
10. D
For 3, in order round the hundredths place up, you would have to have a 5 before it. Therefore, because a 2 is in front of the hundredths place, it can only become 19.87.
When in danger or in doubt, sketch the problem on a number line :)
In number 8, B is the only one that is not a repeater
https://www.google.com/search?q=repeating+decimal+definition&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb
In other words I think question 8 is missing the word "not".
Ms.Sue what do you think about 3 and10?
Brady is right about 3. The answer is 19.87.
Both Brady and I gave you the answer to number 10.
What about #8 I don't see any dots at the end of any numbers.How could I tell which one repeats?
12. The layer of gold coating on a ring should be 0.03 millimeters thick when the ring is completed. A coating of 0.021 millimeters has already been applied. How many more millimeters of gold coating must be added to finish the ring?

B. 0.018 millimeters
C. 0.009 millimeters
D. 0.18 millimeters
C?
Yes. 12. is C.
Please post # 8 as a separate question. Ask for an explanation of a repeating decimal.
For 8, A, C, and D can be a repeating decimal without dots. I have done some researching about this question, and other people are having the same problem. However, most of them had picked D, and they had gotten D right.
12. Correct
