You asked:

Evaluate the expression: \(62.2 + 12.7 \cdot -2\)

MathBot Answer:

\[62.2 + 12.7 \cdot -2 = \frac{184}{5} = 36.8\]


\[\begin{aligned}62.2 + 12.7 \cdot -2& = 62 + \frac{2}{10} + \left(12 + \frac{7}{10}\right) \cdot -2\\& = 62 + \frac{1}{5} + \left(12 + \frac{7}{10}\right) \cdot -2\\& = 62 + \frac{1}{5} + \frac{127}{10} \cdot -2\\& = 62 + \frac{1}{5} - \frac{127}{5}\\& = \frac{311}{5} - \frac{127}{5}\\& = \frac{184}{5}\end{aligned}\]
