Question

1. $-\frac{1}{4}(-8.6)$

Explanation:

Step1: Recall the rule of multiplying two negative numbers

When multiplying two negative numbers, the result is positive. So, \(-\frac{1}{4}(-8.6)\) is equivalent to \(\frac{1}{4} \times 8.6\).

Step2: Calculate the product

We know that \(\frac{1}{4}=0.25\), so we calculate \(0.25\times8.6\).
\(0.25\times8.6 = 2.15\)

Answer:

\(2.15\)
