Question

Which number is irrational? -4 2/9 8.26 11

Answer 1

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.
