It depends. A terminating decimal is a rational number. A decimal which, after a finite number of places, becomes a repeating (or recurrent) decimal is also a rational number. A decimal that is not terminating, nor [eventually] settles into a recurring pattern is not a rational number. Note that the decimal need not become recurring immediately.
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.
No. It is a rational number. Any repeating decimal or terminating decimal is rational.
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.
Decimals are real. They can be rational or irrational.
A number with a finite number of decimal digits is always rational. (If the number of decimal digits is infinite, the number is rational only if there is a repeating pattern.)
Since 2.33333... is a repeating decimal (or recurring decimal), it is a rational number.
A decimal rational number can be expressed as a fraction A decimal irrational number can not be expressed as a fraction
A decimal need not be a rational. A non-terminating, non recurring decimal is an irrational number. Only a terminating decimal or a recurring decimal is rational and that is because such a number can be expressed as a ratio of two integers.
It is a rational number.
