Question

Of the 300 students at Central Middle School, 20% are on the honor roll.

How many students are NOT on the honor roll?

Answer 1

240 isn’t on honor roll

Answer 2

Answer: 240 students

Step-by-step explanation:
For this problem, we know that there are 300 students at this school so we can say that is 100%. Since we know 20% are on the honor roll, then (100% - 20% = )80% are not. Given this, we can say the following:

#ofStudentsNotOnHonorRoll = #ofStudents * %notOnHonorRoll
= 300 * 80%
= 300 * .8
= 240

Hope this helps.

Cheers
