Last week 40 fifth graders went on a field trip to the science museum.
25% of the students went to see the space exhibit. how many students is that?
20 of the fifth graders went to see the technology exhibit.
what fractional part of the group is that?
what percent it that?

25% of the 40 students is 10 students.
first you have to turn 25% into a decimal with is .25. now you have to multiply the number of student with the decimal. 40 x .25 = 10.00 (10 students)

so every 25% is to 10 students.
2o students in percentage is equal to 50% with is 1/2 factional part of the grup.
