Solve question 6 by calculating the reciprocals and performing the operations.

The expression is $\frac{7}{0.9267} - \frac{3}{32.85}$. This can be written as $7 \times \frac{1}{0.9267} - 3 \times \frac{1}{32.85}$.

First, find the reciprocals:

Now, substitute these values back into the expression:

Rounding to four decimal places:
The answer is $\boxed{7.4624}$.

The expression is $28x^{11} \div 7
