Answer
Correct Answer: $1613.4$
Explanation
### Concept & Logic
Moving the decimal point in the denominator of a fraction results in an inverse shift in the overall value of the fraction.
### Step-by-Step Solution
* The given relation is:
$$ \frac{1}{6.198} = 0.16134 $$
* We need to find the value of:
$$ \frac{1}{0.0006198} $$
* Relate the new denominator to the given denominator:
$$ 0.0006198 = 6.198 \times 10^{-4} $$
* Substitute this back into the target fraction:
$$ \frac{1}{6.198 \times 10^{-4}} = \frac{1}{6.198} \times \frac{1}{10^{-4}} $$
$$ = 0.16134 \times 10^{4} $$
* Multiply by $10000$ (shift the decimal $4$ places to the right):
$$ = 1613.4 $$
### Exam Strategy & Shortcut
The denominator decreased by $4$ decimal places (from $6.198$ to $0.0006198$). Making a denominator smaller makes the overall fraction larger. Shift the decimal point of the given answer ($0.16134$) exactly $4$ places to the right to compensate.
### Common Pitfall
Multiplying the given value by $10^{-4}$ instead of $10^{4}$. Remember that a smaller denominator yields a larger result.
### Final Answer
**Therefore, the correct answer is $1613.4$.**
