Question

Suppose 8 out of every 20 students are absent from school less than five days a year. Predict how many students would be from school less than five days a year out of 400 students

Answer 1

160

Explanation:

With the problem, it's best to put this into a fraction

8/20 of every student will be absent from school less than five days a year, which can then be simplified to 2/5.

There are multiple ways to go about this problem, but my preferred way is to then take 1/5th of 400, which can be done by taking 1*400/5 which equals 80. Since we are asking for 2/5's, just multiply that number by 2, which gives us 160 students.
