Answer 1

Nathan Axel

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

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#

To find out how many seventh graders have taken swimming lessons, multiply the total number of seventh graders by the percentage who have taken swimming lessons:

(38% \times 250 = 0.38 \times 250 = 95)

So, 95 seventh graders have taken swimming lessons.
