Question

solve.
-10.6 × -8.05 = □
options: 85.33, -90.10, 81.3, -85.33

Explanation:

Step1: Recall sign rule for multiplication

When multiplying two negative numbers, the result is positive. So \((-10.6)\times(-8.05)\) will be positive.

Step2: Calculate the product

First, calculate \(10.6\times8.05\).
\(10\times8.05 = 80.5\) and \(0.6\times8.05=4.83\).
Then add them: \(80.5 + 4.83=85.33\).
Since both numbers are negative, the product is positive \(85.33\).

Answer:

85.33
