Question

Which number produces an irrational number when added to 1/3?

Answer 1

B

Explanation:

Since all other numbers are rational numbers, and with pi being irrational, adding 1/3 to 2pi would keep it irrational.

Answer 2

2 pi

Explanation:

So lets try and check , why to be lazy ?

1/3+2/3 =1 , as we all know 1 is a rational number.

.

so lets move to another option

Now ,

1/3+2 pi = 7/2 pi , its an irrational number .

we already got the answer , but we will try others too .

( Because i have so much amount of time , let me kill some of it! )

1/3+2 = 2.3333333.... which is again a ratiomal number .

1/3+0.166 = 0.49933333333... which is again a rational number .
