You asked:

Evaluate the expression: \(1.5 \cdot 8.40\)

MathBot Answer:

\[1.5 \cdot 8.40 = \frac{63}{5} = 12.6\]

\[\begin{aligned}1.5 \cdot 8.40& = \left(1 + \frac{5}{10}\right) \cdot \left(8 + \frac{4}{10}\right)\\& = \left(1 + \frac{1}{2}\right) \cdot \left(8 + \frac{4}{10}\right)\\& = \frac{3}{2} \cdot \left(8 + \frac{4}{10}\right)\\& = \frac{3}{2} \cdot \left(8 + \frac{2}{5}\right)\\& = \frac{3}{2} \cdot \frac{42}{5}\\& = \frac{63}{5}\end{aligned}\]
