Answer:

None of them are irrational.

Step-by-step explanation:

An Irrational Number is a real number that cannot be written as a simple fraction.

Therefore:

-4 can be written as -4/1

2/9 is already in fraction

8.26 can be written as 826/100

11 can be written as 11/1

None of them are irrational.

However numbers like $\sqrt{x}, \pi$ are irrational as they can not be represented as fractions.

$2a = 8 - 2 = 6$

$a = 3$
