    Answer: 49 students

    Step-by-step explanation:

    2 / 7 of students in a school wore shorts today. The number of students to be selected in order to get 14 students who will wear shorts to school will be:

    Let the number of students that will be sampled be y. This will be:

    2/7 of y = 14

    2/7 * y = 14

    2y/7 = 14

    Cross Multiply

    2y = 7 * 14

    2y = 98

    y = 98/2

    y = 49

    49 students will be selected randomly.
