Question

to determine a ratio equivalent to the known ratio in this problem, scale down by 4
amia had
animals drool on her.
set up a proportion and use n for the unknown. then solve using means and extremes.
\\(\frac{68}{100} = \frac{n}{25}\\) (animals that drooled / total animals)
\\(\frac{\square}{100} = \frac{\square}{\square}\\) (animals that drooled / total animals)
\\(\square = 100(\square)\\)
\\(\square = n\\)

Explanation:

Step1: Set up the proportion

$$\frac{68}{100}=\frac{n}{25}$$

Step2: Cross - multiply (using means and extremes)

$$68\times25 = 100\times n$$

Step3: Solve for \(n\)

$$n=\frac{68\times25}{100}$$
$$n = 17$$

Answer:

17
