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} $

mathstudent55 · Answer

Now solve the proportion for x by cross multiplying.

Yes

mathstudent55 · Answer

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