alleryStart learning →A number written in decimal form runs on forever with no repeating pattern of digits. What is it?
AIt is rational
BIt is irrational
CIt is an integer
DIt is undefined
Answer & Solution
Correct answer: B. It is irrational
1. To classify a number, first write it in decimal form.
2. If the decimal terminates then the number is rational.
3. If it goes on forever, look for a repeated pattern of digits, which would also make it rational.
4. With no terminating point and no repeated pattern, the number is irrational.
