The number of students who chose floorball, swimming and soccer is repeated. Make the number of students who chose floorball, swimming and soccer the same. LCM of 7 and 5 is 35.
Number of students who chose swimming = 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of more students who chose floorball than badminton
= 21 u - 10 u
= 11 u
= 11 x 12
= 132
Answer(s): 132
