Evaluate the expression: \(-3.6 \cdot 1.225\)

MathBot Answer:

\[-3.6 \cdot 1.225 = - \frac{441}{100} = -4.41\]

\[\begin{aligned}-3.6 \cdot 1.225& = - \cdot \left(3 + \frac{6}{10}\right) \cdot \left(1 + \frac{225}{1000}\right)\\& = - \cdot \left(3 + \frac{3}{5}\right) \cdot \left(1 + \frac{225}{1000}\right)\\& = - \cdot \frac{18}{5} \cdot \left(1 + \frac{225}{1000}\right)\\& = - \cdot \frac{18}{5} \cdot \left(1 + \frac{9}{40}\right)\\& = - \cdot \frac{18}{5} \cdot \frac{49}{40}\\& = - \frac{18}{5} \cdot \frac{49}{40}\\& = - \frac{441}{100}\end{aligned}\]
