To determine which option is an irrational number, we need to understand what an irrational number is. An irrational number is a number that cannot be expressed as a fraction or a ratio of two integers. It cannot be written as a simple fraction or a repeating or terminating decimal.
Looking at the options provided:
A: 0.12*** - This number has a repeating pattern of digits, indicated by the asterisks, which means it can be written as a repeating decimal. Since it can be expressed as a fraction, it is not an irrational number.
B: 0.1257486 - This number is a non-repeating decimal, but it can still be expressed as a finite decimal. It can be written as the fraction 1257486/10000000. Therefore, it is not an irrational number.
C: 0.12121212 - This number has a repeating pattern of digits, and it can be expressed as the fraction 12/99. Therefore, it is not an irrational number.
D: 0.11111 - This number also has a repeating pattern of digits, and it can be expressed as the fraction 1/9. Therefore, it is not an irrational number.
From the given options, none of them are irrational numbers.
