You asked:

Evaluate the expression: \(\frac{12}{3} + \frac{5}{10} \cdot 2.5 - 2\)

MathBot Answer:

\[\frac{12}{3} + \frac{5}{10} \cdot 2.5 - 2 = \frac{13}{4} = 3.25\]

\[\begin{aligned}\frac{12}{3} + \frac{5}{10} \cdot 2.5 - 2& = \frac{12}{3} + \frac{5}{10} \cdot \left(2 + \frac{5}{10}\right) - 2\\& = \frac{12}{3} + \frac{5}{10} \cdot \left(2 + \frac{1}{2}\right) - 2\\& = \frac{12}{3} + \frac{5}{10} \cdot \frac{5}{2} - 2\\& = \frac{12}{3} + \frac{5}{4} - 2\\& = \frac{21}{4} - 2\\& = \frac{13}{4}\end{aligned}\]
