Question

Verify the property $x\times y=y\times x$ of rational numbers by using $x=7$and $y=\frac{1}{2}$.

Answer 1

Verifying the property $x\times y=y\times x$ for given $x$ and $y$:

L.H.S.$=x\times y=7\times \frac{1}{2}=\frac{7}{2}$.

R.H.S $=y\times x=\frac{1}{2}\times 7=\frac{7}{2}$.

On comparing both L.HS. and R.H.S., we get,

$L.H.S=R.H.S.=\frac{7}{2}$

Hence, the property $x\times y=y\times x$ is verified.
