Final answer:
To find the value of s in the equation 1/5 s=5, we multiply both sides by 5 resulting in s = 25. Therefore, the correct answer is D. 25.
Step-by-step explanation:
When solving the equation 1/5 s=5, we are trying to find the value of s that makes the equation true. To do this, we multiply both sides of the equation by 5 to isolate s on one side. This results in the equation s=5*5, which simplifies to s=25. Therefore, the best choice for the value of s is 25, which corresponds to option D.
