You asked:
Evaluate the expression: \(37.80 \cdot 1.21\)
MathBot Answer:
\[37.80 \cdot 1.21 = \frac{22869}{500} = 45.738\]
\[\begin{aligned}37.80 \cdot 1.21& = \left(37 + \frac{8}{10}\right) \cdot \left(1 + \frac{21}{100}\right)\\& = \left(37 + \frac{4}{5}\right) \cdot \left(1 + \frac{21}{100}\right)\\& = \frac{189}{5} \cdot \left(1 + \frac{21}{100}\right)\\& = \frac{189}{5} \cdot \frac{121}{100}\\& = \frac{22869}{500}\end{aligned}\]
