1. Start with the equation:
   
   $$
   33r = 9.9
   $$

2. Solve for $$ r $$ by dividing both sides by 33:

$$
   r = \frac{9.9}{33}
   $$

3. Recognize that $$ 9.9 $$ can be written as a fraction:

$$
   9.9 = \frac{99}{10}
   $$

So, substitute into the equation:

$$
   r = \frac{\frac{99}{10}}{33} = \frac{99}{10 \times 33}
   $$

4. Multiply the denominators:

$$
   r = \frac{99}{330}
   $$

5. Simplify the fraction by dividing the numerator and denominator by 33:

$$
   r = \frac{99 \div 33}{330 \div 33} = \frac{3}{10}
   $$

Therefore, the solution is:

$$
r = \frac{3}{10}
$$
$$ r = \frac{3}{10} $$
