    11/12 times 9/22 - rational

    x + (-2x) unknown

    Step-by-step explanation:

    11/12 is a rational number (the ratio of integers)

    9/22 is a rational number (the ratio of integers)

    11/12 * 9/22 is a rational number

    The product of 2 rational numbers is rational

    x+-2x = x but we do not know if x is rational or irrational, so we cannot say if it is rational or not. If x is rational, the sum is rational. If r is irrational, the sum is irrational.
