Answer 7

"What does "rational" mean here, and how do you recognize a rational number? How do you recognize an irrational number?" Ms-Brains: If you want to understand this problem, you really do need to understand the meaning of "rational" and "irrational." It's disappointing to find that you've typed, "I honestly got no clue." Please, get this info by looking up "rational" and "irrational," OK?

Answer 8

Sure. Gimme 1 sec.

Answer 9

dinamix: If you'd like to help, help Ms-brains undrstand the difference between rational and irrational Do NOT hand out direct answers. Your job is to involved Ms-Brains in finding her own solutions.

Answer 10

i 'm sure about 1/3 and 2/3 cuz only one is rational (logic) @mathmale its logical thinking

Answer 11

Please see my previous comment. Do NOT give out direct answers. You have not verified that Ms-Brains understands what "rational" means.

Answer 12

that's how i understand that @mathmale ok sorry mate

Answer 13

I understand what rational and irrational mean. I'd just like to understand how I can start solving this problem. I've never done a problem such as this one. Does anyone want to try and explain it to me?

Answer 14

Look at the list of numbers. Separate them according to which are rational and which are not.

Answer 15

link data together that's only @mathmale @Ms-Brains

Answer 16

Alright, give me a sec.

Answer 17

Please re-read the problem statement. Then explain in your own words what you're supposed to do. Note the word "added?"

Answer 18

Rational numbers: -6, 2/3, 1/3

Irrational numbers: \[\sqrt{7}\] \[\sqrt[3]{2}\]

Answer 19

Good. Concrete proof that you understand the difference between rational and irrational.

Now, take -6 and add sqrt(7). Is this sum rational or irrational?

Take -6 and add 2/3. Is the sum rational or irrational?

You have to list all combinations that are rational.

Answer 20

Okay.
