28 students in a class, 7 went on a trip. What percent went on the trip
100 * 7 / 28 = 25%
To find the percentage of students that went on the trip, you need to divide the number of students who went on the trip by the total number of students in the class, and then multiply the result by 100.
Number of students who went on the trip: 7
Total number of students in the class: 28
Percentage of students who went on the trip = (Number of students who went on the trip / Total number of students in the class) * 100
Substituting the values:
Percentage of students who went on the trip = (7 / 28) * 100
Simplifying the expression:
Percentage of students who went on the trip = 0.25 * 100
Percentage of students who went on the trip = 25%
Therefore, 25% of the students in the class went on the trip.
