Mean is the same thing as averageexamplethe mean of 30 and 40 is 35 because (30+40)/2=70/2=35mean absolue deviation is when you take the mean of the setthen you find the diffference of each number of the set then take the mean of thatex if yo uhave 1,2,3,4,5 and the mean is 3, then ou find the absolute value of the difference of each|1-3|=2|2-3|=1|3-3|=0|4-3|=1|5-3|=2add them and divide by 5(2+1+0+1+2)/5=6/5= mad=6/5

If 1/5 of the students are in the football team and the class has 40 students, you need to multiple this numbers to know the exact number of students that form the team.40 x 1/5 = 8 studentsif 4 more students join: 8+4= 12 studentsto know the %: 40 students are equivalent to the whole class (100%). then 12 students are how much %? 40 students  = 100%12 students  =    x  %x= 30% of students are in the team.
