MathBot Answer:

3⋅9−18−(7⋅27)+5⋅9=151421=72.095238‾3 \cdot 9 - \frac{18}{-\left( 7 \cdot 27 \right)} + 5 \cdot 9 = \frac{1514}{21} = 72.\overline{095238}

3⋅9−18−(7⋅27)+5⋅9=27−18−(7⋅27)+5⋅9=27−18−189+5⋅9=27−−221+5⋅9=56921+5⋅9=56921+45=151421\begin{aligned}3 \cdot 9 - \frac{18}{-\left( 7 \cdot 27 \right)} + 5 \cdot 9&=27 - \frac{18}{-\left( 7 \cdot 27 \right)} + 5 \cdot 9\\&=27 - \frac{18}{-189} + 5 \cdot 9\\&=27 - \frac{-2}{21} + 5 \cdot 9\\&=\frac{569}{21} + 5 \cdot 9\\&=\frac{569}{21} + 45\\&=\frac{1514}{21}\end{aligned}
