Verify the commutative property — task. Maths CBSE Live product, Class 9 (2026-27).

(i) Verify whether addition is commutative for

\frac{23}{5}

and

\frac{-19}{9}

Answer:

(\frac{23}{5} + \frac{-19}{9})

$=$

\frac{i}{i}

(\frac{-19}{9} + \frac{23}{5})

$=$

\frac{i}{i}

Thus,

(\frac{23}{5} + \frac{-19}{9})

(\frac{-19}{9} + \frac{23}{5})

(ii) Verify whether multiplication is commutative for $\frac{9}{5}$ and $\frac{3}{17}$ .

Answer:

(\frac{9}{5} \times \frac{3}{17})

$=$

\frac{i}{i}

(\frac{3}{17} \times \frac{9}{5})

$=$

\frac{i}{i}

(\frac{9}{5} \times \frac{3}{17})

(\frac{3}{17} \times \frac{9}{5})

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