(i) Verify whether addition is commutative for

\frac{13}{5}

and

\frac{-2}{9}

Answer:

(\frac{13}{5} + \frac{-2}{9})

$=$

\frac{i}{i}

(\frac{-2}{9} + \frac{13}{5})

$=$

\frac{i}{i}

Thus,

(\frac{13}{5} + \frac{-2}{9})

(\frac{-2}{9} + \frac{13}{5})

(ii) Verify whether multiplication is commutative for $\frac{14}{2}$ and $\frac{3}{13}$ .

Answer:

(\frac{14}{2} \times \frac{3}{13})

$=$

\frac{i}{i}

(\frac{3}{13} \times \frac{14}{2})

$=$

\frac{i}{i}

(\frac{14}{2} \times \frac{3}{13})

(\frac{3}{13} \times \frac{14}{2})

[Note: Submit the answer without simplifying the fraction.]
