Question : Say true or false. $\frac{1}{0}$ is not rational.

1. True
2. False

Solution :
The correct option is 1. True
A rational number is a number that can be defined in the form of $\frac{p}{q}$, where $q$ is nonzero.
Now, if $\mathrm{q}$ is 0 , although an integer, the solution will not be a rational number. It will give an undefined result, so the statement is true.
