Question

Simplify the following.

$\left(-54\right)of\left(-9\right)+52÷\left(-7\right)$

Answer 1

$$\begin{gathered} \left(-54\right)of\left(-9\right)+52÷\left(-7\right)=54\times 9+\frac{52}{-7} \\ =486+\frac{52}{-7} \\ =\frac{486\times \left(-7\right)+52}{-7} \\ =\frac{-3402+52}{-7} \\ =\frac{-3350}{-7}\Rightarrow \frac{3350}{7} \end{gathered}$$

Hence, the required answer is $\frac{3350}{7}.$
