Step 1: 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: $$ \frac{1}{0.9267} \approx 1.079108665 $$ $$ \frac{1}{32.85} \approx 0.030441399 $$ Now, substitute these values back into the expression: $$ 7 \times (1.079108665) - 3 \times (0.030441399) $$ $$ 7.553760655 - 0.091324197 $$ $$ 7.462436458 $$ Rounding to four decimal places: The answer is $\boxed{7.4624}$. Step 2: Simplify question 7 part i). The expression is $28x^{11} \div 7
