Explanation:

To determine the number of adults required for 75 kids, we set up a proportion using the given ratio and solve for the unknown number of adults. The correct answer is 12 adults.

To determine the number of adults required for 75 kids, we need to follow the given ratio of 4 adults for every 25 kids. We can set up a proportion to solve for the unknown number of adults:

4 adults / 25 kids = x adults / 75 kids

Cross-multiplying gives us:

(4 adults)(75 kids) = (25 kids)(x adults)

300 adults = 25x

To solve for x, we divide both sides of the equation by 25:

x = 12 adults

Therefore, 12 adults are required for 75 kids.
