Evaluate the expression: \(1.12 \cdot -38.3\)

MathBot Answer:

\[1.12 \cdot -38.3 = - \frac{5362}{125} = -42.896\]

\[\begin{aligned}1.12 \cdot -38.3& = \left(1 + \frac{12}{100}\right) \cdot -1 \cdot \left(38 + \frac{3}{10}\right)\\& = \left(1 + \frac{3}{25}\right) \cdot -1 \cdot \left(38 + \frac{3}{10}\right)\\& = \frac{28}{25} \cdot -1 \cdot \left(38 + \frac{3}{10}\right)\\& = \frac{28}{25} \cdot -1 \cdot \frac{383}{10}\\& = - \frac{28}{25} \cdot \frac{383}{10}\\& = - \frac{5362}{125}\end{aligned}\]
