Question

Find using additive inverse property, what should be added to $\frac{-1}{3}$, so that the sum is zero ?

• A. $\frac{-1}{3}$
• B. $\frac{1}{3}$
• C. $1$
• D. $0$

Answer 1

The correct option is B $\frac{1}{3}$

We know that the sum of a rational number and its additive inverse is zero.

Since the given rational number is $\frac{-1}{3}$, its negative is $-\left(\frac{-1}{3}\right)=\frac{1}{3}$

Now, $\frac{-1}{3}+\frac{1}{3}=0$. Hence, $\frac{1}{3}$ should be added to $\frac{-1}{3}$ to get the sum as $0$.
