What is a real number between five ninths and 6 ninths?

Answer 1

There are infinitely many real numbers between 5/9 and 6/9.

One of the ways to find a real number between 5/9 and 6/9 is multiplying numerators and denominators of both numbers by an integer.

5/9 x 3/3 = 15/27

6/9 x 3/3 = 18/27

Now we have two more rational numbers to state which are 16/27 and 17/27.

If we multiply by a larger then we get more numbers between 5/9 and 6/9.

So we can say that we can have infinite real numbers.
