7. Write three numbers whose decimal expansions are non-terminating non-recurring.

Question:

Write three numbers whose decimal expansions are non-terminating non-recurring.

Answer:

We know that all the rational numbers are non-terminating non-recurring. So, three numbers whose decimal expansions are non-terminating non-securring are: 0.04004000400004..., 0.505005000500005... and 0.007000700007...
