Question

Select all numbers that are irrational.

A. √144

B. √8

C. 16π

D. 0.45

Answer 1

I think it's A and D.

Answer 2

Irrational Numbers:
A real number that can NOT be made by dividing two integers. (Note: integers have no fractions.) The decimal goes on forever without repeating. Example: Pi is an irrational number.

Answer 3

just to be clearer, adding on to Lemon


if a number can be written as a fraction, like this, where A and B are integers (whole numbers), it is rational

for example

3 is a rational number, because we can write it as a fraction of integers, 3/1=3

6/4 is a fraction of integers, hence rational
