## JokerSmart one year ago which number is irrational? A. 0.27 B. 1/9 C. 12 D. 64/4

Well i believe that we can cancel out B and D because fractions can not be irrational This will help you decide All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.

$A. 0.270$ $B. \frac{ 1 }{ 9 }$ $C. \sqrt{12}$ $D. \frac{ 64 }{ 4 }$

I want you to convert all the answers into decimals if you can do so.

4. JokerSmart

Is it A?

5. anonymous

no it is not A because it is not repeating

I want you to divide 26 by 3 and tell me what you get

8.666666666666667. There's a lot of 6's.

that is a example of a irrational number, the decimal goes on for infinity. Your answer when in decimal form will look like this.

So you should convert all of the answers into decimals then compare and find the irrational number
