Solution

Evaluate the expression \(1.8jk\) for \(j = -1\) and \(k = 2\). Substitute the values of \(j\) and \(k\) into the expression: \[ 1.8 \times (-1) \times 2 \] Calculate the multiplication: First, multiply \(1.8\) and \(-1\): \[ 1.8 \times (-1) = -1.8 \] Next, multiply \(-1.8\) and \(2\): \[ -1.8 \times 2 = -3.6 \] The answer is \(-3.6\).
