You asked:

Evaluate the expression: \(2.5 + 2.7 - 2.4\)

MathBot Answer:

\[2.5 + 2.7 - 2.4 = \frac{14}{5} = 2.8\]


\[\begin{aligned}2.5 + 2.7 - 2.4& = 2 + \frac{5}{10} + 2 + \frac{7}{10} - \left(2 + \frac{4}{10}\right)\\& = 2 + \frac{1}{2} + 2 + \frac{7}{10} - \left(2 + \frac{4}{10}\right)\\& = 2 + \frac{1}{2} + 2 + \frac{7}{10} - \left(2 + \frac{2}{5}\right)\\& = 2 + \frac{1}{2} + 2 + \frac{7}{10} - \frac{12}{5}\\& = \frac{5}{2} + 2 + \frac{7}{10} - \frac{12}{5}\\& = \frac{9}{2} + \frac{7}{10} - \frac{12}{5}\\& = \frac{26}{5} - \frac{12}{5}\\& = \frac{14}{5}\end{aligned}\]
