Last Thursday was costume day at Wayne's school. 20 out of the 100 students at the school wore a costume. What percentage of the students wore a costume?

20 percent or 2/10

Step-by-step explanation:

to make into a percentage it would be easy because of it being out of 100 so make the 100 a percentage and then see how much the 20 would be it would be the same 20/100 only in percentage form so 20 percent
