The number of students who chose squash, floorball and gymnastics is repeated. Make the number of students who chose squash, floorball and gymnastics the same. LCM of 7 and 5 is 35.
Number of students who chose floorball = 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Number of more students who chose squash than jogging
= 21 u - 10 u
= 11 u
= 11 x 10
= 110
Answer(s): 110
