Question

suppose 8 out of every 20 students are absent from school less than five days a year. Predict how many students would be absent from school less than five days a year out of 40,000 students.

Answer 1

8/20*40,000

2/5*40,000

80,000/5

160,000/10

16,000 students

Answer 2

we have that

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

then

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

By proportion

`(8)/(20) =(x)/(40,000) \\\\ 20*x= 8*40,000\\\\ x=(8*40,000)/(20)`

`x= 16,000\ students`

therefore

the answer is

`16,000\ students`
