You asked:

Evaluate the expression: \(22.5 \cdot 12.4\)

MathBot Answer:

\[22.5 \cdot 12.4 = 279\]


\[\begin{aligned}22.5 \cdot 12.4& = \left(22 + \frac{5}{10}\right) \cdot \left(12 + \frac{4}{10}\right)\\& = \left(22 + \frac{1}{2}\right) \cdot \left(12 + \frac{4}{10}\right)\\& = \frac{45}{2} \cdot \left(12 + \frac{4}{10}\right)\\& = \frac{45}{2} \cdot \left(12 + \frac{2}{5}\right)\\& = \frac{45}{2} \cdot \frac{62}{5}\\& = 279\end{aligned}\]
