You asked:

Evaluate the expression: \(144.735 \cdot -0.15\)

MathBot Answer:

\[144.735 \cdot -0.15 = - \frac{86841}{4000} = -21.71025\]

\[\begin{aligned}144.735 \cdot -0.15& = \left(144 + \frac{735}{1000}\right) \cdot -1 \cdot \frac{15}{100}\\& = \left(144 + \frac{147}{200}\right) \cdot -1 \cdot \frac{15}{100}\\& = \frac{28947}{200} \cdot -1 \cdot \frac{15}{100}\\& = \frac{28947}{200} \cdot -1 \cdot \frac{3}{20}\\& = - \frac{28947}{200} \cdot \frac{3}{20}\\& = - \frac{86841}{4000}\end{aligned}\]
