Answer: 1) 40%
2) 57.14%
3) 16%
Explanation:
1). Total students in 8th grade is = 8+2+12+3+5 = 30
Number of students who said football is their favorite sport = 12
Therefore % of these students = (Number of students who play football/Total students)×100 = (12/30)×100 = 1200/30 = 40%
2). In 8th grade number of students who said baseball is their favorite sport = 8
In 9th grade number of students who said baseball is their favorite sport = 6
Total students having favorite sport was baseball = 8+6=14
Therefore % of students in grade 8 out of total students = (8/14)×100 = 800/14 = 57.14%
3). In 9th grade total number of students = 6+3+10+2+4 =25
Students who said soccer is their favorite sport = 4
Therefore % of these students = (4/25)×100 = 16%
