    Answer:

    We have 250 sixth-grade students are at the school

    Step-by-step explanation:

    Let the total number of sixth graders be represented as x

    Therefore we solve the question nas shown below:

    40% of x = 100 sixth grade students that prefer Hip -pop

    = 40/100 × x = 100

    = 40x /100 = 1000

    Cross y

    40x = 100 × 100

    40x = 10000

    x = 10000/40

    x = 250 students

    Hence, we have 250 sixth-grade students are at the school
