Evaluate the expression: \(9.7 \cdot 9.8\)

MathBot Answer:

\[9.7 \cdot 9.8 = \frac{4753}{50} = 95.06\]

\[\begin{aligned}9.7 \cdot 9.8& = \left(9 + \frac{7}{10}\right) \cdot \left(9 + \frac{8}{10}\right)\\& = \frac{97}{10} \cdot \left(9 + \frac{8}{10}\right)\\& = \frac{97}{10} \cdot \left(9 + \frac{4}{5}\right)\\& = \frac{97}{10} \cdot \frac{49}{5}\\& = \frac{4753}{50}\end{aligned}\]
