About 6 out of 10 people entering a community college need to take a refresher mathematics course. if there are 850 enteringâ students, how many will probably need a refresher mathematicsâ course?

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
