"In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number."

i hope this helps.

it can be written as a mixed fraction which is still a fraction. so yes, it is rational
