6 0

First you find 0.5% of 639 = 0.5/100=x/639
Or 0.5*639/100
This would be 3.195
Second you round 3.195 to the nearest whole number which would be 3
So 3 students attended the camp two years in a row.

Answer:

First of all, he have to find out what 0.5% of the students is.

Second of all, find out what 0.5 of 100 is. 100 divided by 0.5 is 200.

Third of all, divide 200 from 639. This equals 3.195

Since it is asking about how many, I would go with about 3. After all, you can't have have half of a person, so the decimals shouldn't be added.
