Suppose
8 out of every 20 students are absent from school less than five days a year.

The ratio then is 8 : 20

Predict how many students would be absent from school less than five days a
year out of 40,000 students.

So the ratio now is: 8 : 20 = x : 40 000

=> 40 000 * 8 = 320 000 / 20 = 16 000

=> 8 : 20 = 16 000 : 40 000
