Question

If X/Y and Y/X are rational numbers, then which of the following option is correct

X can be 0, Y≠0
X ≠ 0,Y≠ 0
Both X and Y can be 0​

CONCEPT TO BE IMPLEMENTED

A Rational number is defined as a number of the form $\frac{p}{q}$Where p & q are integers with $q \ne \: 0$

EXAMPLE

$2,3, - 1, \frac{1}{3} , - \frac{12}{23}$are the examples of rational numbers

TO DETERMINE

If $\frac{X}{Y}$ and $\frac{Y}{X}$are rational numbers, then which of the following option i

Both X and Y can be 0

CALCULATION

Since $\frac{X}{Y}$is rational

So by the definition of rational numbers $Y \ne \: 0$

Again $\frac{Y}{X}$is rational

So by the definition of rational numbers $X \ne0$

So the correct option is $X \ne \: 0 \: \: \: \: and \: \: \: Y \ne \: 0$
