The set of all multiples of 7?​

I hope that’s what you were looking for:)

1 absence = 45%
2 absences = 21%
no absences = 23%
added = 89%
so 3 or more absences = (100% - 89%) = 11%

96 students had 2 or more absences2 or more absences = (21% + 11%) = 32%
so 96 of the total students = 32%32% of what is 96...
0.32x = 96
x = 96/0.32
x = 300
so there are a total of 300 students..

how many students had 1 absence ?
45% of 300 had 1 absence
0.45(300) = 135 students had 1 absence <
