Answer
An irrational number is a real number which can be written as a decimal but not as a fraction i.e. it cannot be expressed as a ratio of integers. It cannot be expressed as terminating or repeating decimal. For example, 0.10110100 is an irrational number. A rational number is a real number which can be written as a fraction and as a decimal i.e. it can be expressed as a ratio of integers. It can be expressed as terminating or repeating decimal. For examples,$0.10$ and $0.\bar{4}$ both are rational numbers.
