what type of numbers are between 3.1 and 3.9 on the number line?

Question

I don't get this

Answer 1

Any Real numbers between 3.1 and 3.9--even the transcendental number pi, which is beyond irrationality in classification.

Answer 2

There are many types of numbers.  In this case, you will have only irrational and rational numbers.  The reason for this is because in this range of numbers, you have values of different accuracy.  By accuracy, I mean significant digits after the decimal point.

 

Think of numbers between  3.100000000000000 and 3.9000000000000000
