Question

solve (8.5)·(-3)=a.
a =
(lesson 5-15)

Explanation:

Step1: Recall multiplication rule for signs

When multiplying a positive number by a negative number, the result is negative. So, \(8.5\times(-3)\) will be negative.

Step2: Multiply the absolute values

Multiply \(8.5\) and \(3\). \(8.5\times3 = 25.5\)

Step3: Apply the sign

Since one number is positive and the other is negative, the result is \(-25.5\). So, \(a = -25.5\)

Answer:

\(-25.5\)
