Basket : 1/4 = (6*1)/(6*4) = 6/24
Tennis : 1/6 = (4*1)/(4*6) = 4/24
Football : 3/8 = (3*3)/(3*8) = 9/24
Danse : 1/12 = (2*1)/(2*12) = 2/24
Handball : 1/8 = (3*1)/(3*8) = 3/24

2/24 < 3/24 < 4/24 < 6/24 < 9/24
Danse < Handball < Tennis < Basket < Football

Danse : Vert / Handball : Violet / Tennis : Bleu / Basket : Rose / Football : Orange

b)
Danse : (1/12)*72 = 72/12 = 6 adhérents
   
Handball : (1/8)*72 = 72/8 = 9 adhérents
 
  Tennis : (1/6)*72 = 72/6 = 12 adhérents
   
Basket : (1/4)*72 = 72/4 = 18 adhérents
    Football : (3/8)*72 = 216/8 = 27 adhérents
