Find the product of the additive inverse and multiplicative inverse of 1
                                                                                                               3

Please find below the solution to the asked query:

Additive inverse of $\frac{1}{3} = \mathbf{-}\frac{\mathbf{1}}{\mathbf{3}}$ .

Multiplicative inverse of $\frac{1}{3} = \frac{\mathbf{3}}{\mathbf{1}}$

So,

Product of these = $-\frac{1}{3}\times \frac{3}{1} =\mathbf{ }\mathbf{-}\mathbf{1}$                                 ( Ans )
