Answer 1

Notice that the number of students that got a grade below 80 is:

`7,`

and the total number of students is:

`20.`

Therefore, we have to determine what percentage 7 represents from 20. To determine the percentage that x represents from y, we can use the following expression:

`(x)/(y)*100.`

Finally, we get that 7 represents the

`(7)/(20)*100=35\%,`

of 20.

Answer:

`35\%.`
