At a middle school, 38% of all seventh graders have taken swimming lessons. There are 250 students in the seventh grade. How many of them have taken swimming lessons?

1 Answer

Answer:

#95# students in the seventh grade have taken swimming lessons.

Explanation:

We calculate #38%# of #250# using the following formula:

#x=250xx38/100#

#x=25cancel0xx38/(10cancel0)" "#(cancel by 10)

#x=5cancel25xx38/(2cancel10)" "#(cancel by 5)

#x=5xx(19cancel38)/(1cancel2)" "#(cancel by 2)

#x=5xx19#

#x=95#
