Answer:
Step-by-step explanation:
A number with a non-terminating, non-repeating decimal fraction is irrational. The "..." at the end of the decimal fraction means the number continues indefinitely.
If there are repeated digits ahead of that, then the ... may indicate they continue to repeat, as in 0.727272... . The first and last of the choices given here do not seem to be repeating decimals, so should be considered irrational.
