Q. What is the sign of −5⋅(−1−2) -5 \cdot\left(\frac{-1}{-2}\right) ?\newlineChoose 11 answer:\newline(A) Positive\newline(B) Negative\newline(c) Zero
  1. Multiply and Calculate: Now, we multiply −5-5 by the result we just got, which is 12\frac{1}{2}. So, −5×(12)-5 \times \left(\frac{1}{2}\right) equals −2.5-2.5.
  2. Determine Sign: Since −2.5-2.5 is less than zero, the sign of the expression is negative.
