Yes, a rational number is of the form $\frac{a}{b}$ where $a,b\in\mathbb{Z}$ and $b\ne0$.

In other words, an integer divided by a non-zero integer is a rational number.

Re: rational number!
Yeah It is a rational Number as it's in the form of a/b,where a,b belongs to Z and b is not equal to 0
i.e. a number which can be written in a simple fraction is known as rational numbers.
