    Answer:510 students

    Explanation: given that total student is 850

    And Of every 10 student 6 will have to sit for a refresher math course

    Hence the number that will need a refresher math course will be (850/10) * 6 = 510

    Or better still to better understand this let's use the crossing multiplication method

    of 10 student 6must do a refresher math then

    Of 850 students x must do a refresher math

    Cross multiplying we have

    X = (850*6) / 10=510 students
