The number of students who chose squash, canoeing and basketball is repeated. Make the number of students who chose squash, canoeing and basketball the same. LCM of 7 and 5 is 35.
Number of students who chose canoeing = 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of more students who chose squash than gymnastics
= 21 u - 10 u
= 11 u
= 11 x 2
= 22
Answer(s): 22
