Q. What is the sign of

\frac{23}{45}+\left(-\frac{23}{45}\right) ?

\newline

Choose

answer:

\newline

(A) Positive

\newline

(B) Negative

\newline

(C) Neither positive nor negative-the sum is zero.

Identify Numbers: Identify the numbers involved in the addition. $\newline$ We have two fractions: $\frac{23}{45}$ and $-\left(\frac{23}{45}\right)$ . The second fraction is the negative of the first one.
Add Fractions: Add the two fractions. $\newline$ Since the fractions have the same denominator, we can add them directly. $\newline$ $(\frac{23}{45}) + (-(\frac{23}{45})) = \frac{23}{45} - \frac{23}{45}$
Calculate Sum: Calculate the sum. $\frac{23}{45} - \frac{23}{45} = 0$ The positive and negative versions of the same number cancel each other out.
Determine Sign: Determine the sign of the result. $\newline$ Since the sum is $0$ , it is neither positive nor negative.
