You asked:

Evaluate the expression: \(10.90 \cdot 4.50\)

MathBot Answer:

\[10.90 \cdot 4.50 = \frac{981}{20} = 49.05\]

\[\begin{aligned}10.90 \cdot 4.50& = \left(10 + \frac{9}{10}\right) \cdot \left(4 + \frac{5}{10}\right)\\& = \frac{109}{10} \cdot \left(4 + \frac{5}{10}\right)\\& = \frac{109}{10} \cdot \left(4 + \frac{1}{2}\right)\\& = \frac{109}{10} \cdot \frac{9}{2}\\& = \frac{981}{20}\end{aligned}\]
