Bonjours a tous J ai 11 ans besoin d aide; Transforme ces pourcentages en fractions; 50% - 75% - 100% - 200% - 20% :

50% = 1/2
75% = 3/4
100% = 1/1
200% = 2/1
20% = 1/5

50% = 50/100 = (1*50) / 2*50 = 1/2
75%= 75/100 = (3*25) / (4*25) = 3/4
100% = 100/100 = 1/1 ou 1
200% = 200/100 = (2*100 ) / 100 = 2/1 ou 2
20/100 = (1*20) / (5*20)  = 1/5
