You asked:

Evaluate the expression: \(3.6 \cdot 4.1 + 6.2\)

MathBot Answer:

\[3.6 \cdot 4.1 + 6.2 = \frac{524}{25} = 20.96\]


\[\begin{aligned}3.6 \cdot 4.1 + 6.2& = \left(3 + \frac{6}{10}\right) \cdot \left(4 + \frac{1}{10}\right) + 6 + \frac{2}{10}\\& = \left(3 + \frac{3}{5}\right) \cdot \left(4 + \frac{1}{10}\right) + 6 + \frac{2}{10}\\& = \frac{18}{5} \cdot \left(4 + \frac{1}{10}\right) + 6 + \frac{2}{10}\\& = \frac{18}{5} \cdot \frac{41}{10} + 6 + \frac{2}{10}\\& = \frac{369}{25} + 6 + \frac{2}{10}\\& = \frac{369}{25} + 6 + \frac{1}{5}\\& = \frac{519}{25} + \frac{1}{5}\\& = \frac{524}{25}\end{aligned}\]
