Question

Which of the following is an irrational number?

A.) 38/5

B.) 24 3/13

C.) 13.627497...

D.) 17.25

Answer 1

Note that 38/5, 24 3/13 and 17.25 are all rational numbers; they can all be expressed as ratios of two integers.  

On the other hand, 13.627497... is a repeating decimal (we know that because of the " ... " at the end), and cannot be expressed as the ratio of two integers.

Answer 2

Answer:

13.627497...

Step-by-step explanation:

Because an irrational number is repeated and does not have a pattern to it.
