Percent is a ratio out of 100. You are given a ratio of 8 out of 1600. You want to know what ratio out of 100 that equals. Set up a proportion: 8 out of 1600 equals x out of 100 $$\dfrac{8}{1600} = \dfrac{x}{100}$$

Now solve the proportion for x by cross multiplying.

0.5?

Yes

$$1600x = 8 \times 100$$ $$1600x = 800$$ $$x = \dfrac{800}{1600}$$ $$x = 0.5$$ Answer: 0.5% You are correct.
