What do you do to check whether a number is rational or irrational? In your explanation, use an example of an irrational and a rational number.

Question

Please help me I don't know what to do.

Answer 1

any number that can be expressed as a simple fraction of the form a/b, where b ≠ 0 is rational

rational --- from ratio --- a: b or a/b

A number which cannot be expressed as a simple fraction in the above form is irrational
irrational --> not rational
(irresponsible -- not responsible)

Any decimal which terminates is rational
any decimal which has a repeat is rational
any decimal which does not show any repeating decimals and which is never-ending is irrational

e.g.
4/7 --- rational
3.454545... rational
2.6789789789... rational
4.56556555655556... irrational
π --- irrational
√5 or any square root of a number which is not a perfect square is irrational

√16 -- rational, but √17 -- irrational

Answer 20

yall its okay to look up your answers all this junk we learning will never be used irl so pls stop bashing other ppl you fools. A LOT of celebrities didnt go to college didnt do real work in school and cheated so to the people who are feeling bad jus dont your fine. jus make sure you dont come out of school sounding dumb asl.

Answer 21

a girl, how much money do you want to bet these celebrities don't know what an irrational number is. Yes, you won't need this stuff if you ae going to study rocks. But what if that on time, that one time, you need to know how to solve one. Now the whole celebrities stuff. Most celebrities are famous because of how they look, or how good their acting is in a movie. You look at someone like Tom Cruise. He only acts, but he is still an incredibly smart man. Now other celebrities such as the Kardashians will be forgotten in 50 years. But someone like Elon Musk won't be forgotten because of what he has done.

Answer 22

yes

a irrational number is a never ending number, a rational number is a ending number.

Answer 42

I am not a math teacher and the explanation given for this question is so confusing. Why would anyone want to copy this information? You can't even explain the steps. Just define what rational and irrational numbers are and then give an example.

Answer 43

how are we going the hell for checking are answers???

Answer 44

well...thanks alot T_T

Answer 45

Guys are you all brain dead? "*eats popcorn* hehe funny lol, nom nom hehe. "WE WILL FIND YO BUM AN EXPELS YA!!" lol "U BRAKIN RULS AND U IS BADS"" Go back to 2009. And we are here to cheat.. all of us. We already know that so you don't have to say "This thread has me dyinggg stop pretending y’all accidentally got here WE ALL HERE TO CHEAT" because no one cares. It's a known fact that you can cheat on most things in school just not the the base stuff. If you you already know what you want to be in life then that's all the more true. Once you past school or in collage the things you learned in 8th grade you won't even remember.. So in short don't post unless you got something to share.

Rational numbers are those numbers that are integers and can be expressed in the form of x/y where both numerator and denominator are integers whereas irrational numbers are those numbers which cannot be expressed in a fraction. 🙂
