You asked:

Evaluate the expression: \(-12 + 1\frac{2}{3} + -4 - \frac{5}{7} \cdot -2\frac{4}{5}\)

MathBot Answer:

\[-12 + 1\frac{2}{3} + -4 - \frac{5}{7} \cdot -2\frac{4}{5} = - \frac{37}{3} = -12.\overline{3}\]

\[\begin{aligned}-12 + 1\frac{2}{3} + -4 - \frac{5}{7} \cdot -2\frac{4}{5}& = -12 + 1\frac{2}{3} - 4 - \frac{5}{7} \cdot - \frac{14}{5}\\& = -12 + 1\frac{2}{3} - 4 - -2\\& = -12 + 1\frac{2}{3} - 4 + 2\\& = - \frac{31}{3} - 4 + 2\\& = - \frac{43}{3} + 2\\& = - \frac{37}{3}\end{aligned}\]
