Can you use a calculator to determine if a number is rational or irrational

Yes becasue if the number is irrational it would look something like this on a calculator 4.467833463983 that number never stops so its irrational if its rational it could look some like this 4.46 its rational because it stops or another rational would be 4.46464646464 because its the same two number repaeating if it repeats then it would be rational

Yes because I had a test on that too when I put yes it was the write answer
