1. The problem is to solve the equation $$\frac{s}{6} = 2.5$$ for $s$. 2. The formula used here is to isolate $s$ by multiplying both sides of the equation by 6, the denominator of the fraction. 3. Multiply both sides by 6: $$s = 2.5 \times 6$$ 4. Calculate the right side: $$s = 15$$ 5. Therefore, the solution to the equation $$\frac{s}{6} = 2.5$$ is $$s = 15$$. This means that when $s$ is 15, dividing it by 6 gives 2.5.
