Question 108(i)
Verify the property $x\times y=y\times x$ of rational numbers by using $x=7$ and $y=\frac{1}{2}$

Answer 1

Given: $x=7andy=\frac{1}{2}$

Then,
$LHS=x\times y=7\times \frac{1}{2}=\frac{7}{2}$

$RHS=y\times x=\frac{1}{2}\times 7=\frac{7}{2}$

$\therefore LHS=RHS\Rightarrow x\times y=y\times x$

Hence verified.
