You asked:

Evaluate the expression: \(\left(3 + \frac{1}{4}\right) \cdot \left(3 - \frac{4}{5}\right)\)

MathBot Answer:

\[\left(3 + \frac{1}{4}\right) \cdot \left(3 - \frac{4}{5}\right) = \frac{143}{20} = 7.15\]

\[\begin{aligned}\left(3 + \frac{1}{4}\right) \cdot \left(3 - \frac{4}{5}\right)& = \frac{13}{4} \cdot \left(3 - \frac{4}{5}\right)\\& = \frac{13}{4} \cdot \frac{11}{5}\\& = \frac{143}{20}\end{aligned}\]
