1. The problem states the formula: $T = \frac{k}{n}$. 2. This formula means that $T$ is directly proportional to $k$ and inversely proportional to $n$. 3. To understand or use this formula, you need values for $k$ and $n$. 4. If you want to solve for $k$, multiply both sides by $n$: $$k = T \times n$$. 5. If you want to solve for $n$, multiply both sides by $n$ and then divide both sides by $T$: $$n = \frac{k}{T}$$. 6. This formula is useful in problems involving ratios or rates where one quantity varies inversely with another. 7. Without specific values, this is the general form and explanation of the formula.
