No.

-22/9 is a fraction with integer numerator and denominator. That is the definition of a rational number. When written in decimal form, it is an infinitely repeating decimal with a single repeating digit: 4. Any repeating decimal is a rational number. It is only irrational if it doesn't repeat.
