?

\newline

Choose

1

answer:

\newline

(A) Positive

\newline

(B) Negative

\newline

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

Determine Sign: We need to determine the sign of the sum of two numbers: $-49.8$ and $61.2$ . To do this, we will add the two numbers together. $\newline$ Calculation: $-49.8 + 61.2$
Perform Addition: Since $61.2$ is greater than $49.8$ , and we are adding a negative number to a positive number, the result will be positive because the absolute value of $61.2$ is greater than the absolute value of $-49.8$ . $\newline$ Calculation: $61.2 - 49.8 = 11.4$ , which is positive.
