6 students were absent and this is because 1/5 (one fifth) = 6 students 1/5 x 4 (as there are four fifths) = 24 30 - 24 = 6
Hope that helped :)
24 present because 30/5 = 6 so 6x4 =24 so 24 students mate
In a class of 30 students, if four-fifths are present, then 6 students are absent. This is found by calculating the number of students present, which is 24, and subtracting that from the total of 30. Thus, the formula used is 30 − 24 = 6 .
