Question

Classify the following number as rational or irrational: (a) 3.567523 ​

Answer 1

Answer: it's a rational number

Step-by-step explanation:

See if it was an irrational number then it will have a decimal expansion like this

3.1235940720351803.......

With no definite pattern

And rational numbers are having terminating or non repeating decimal expansion like

3.1415 Or 3.33333.....

Or 3.232323...

They either terminate after sometime or have a definite pattern.

Hence similarly 3.567523 which is having a terminating decimal expansion is a rational number.
