Rosa Mora · Answer 1

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.
