Question

$\frac{x}{y}$ and $\frac{y}{x}$ are rational numbers, then x = 0, 1, 2, 3,.....but x cannot be negative number.

• A. x ≠ 0, y can be 0
• B. x can be 0, y ≠ 0

Answer 1

The correct option is B

x can be 0, y ≠ 0

A rational number cannot have its denominator as 0. As $\frac{x}{y}$ and $\frac{y}{x}$ are rational numbers, $x\ne 0,y\ne 0$.
