Réponse :
E = 3/5 x 7/14
E = (3x7)/(5x7x2) = 21/70 = (3x7)/(10x7) = 3/7
F = 2/3 x 15/20
F = (2x15)/(3x2x10) = 30/60 = 1/2
G = 15/6 x 9/40 = (15x9)/(6x5x8) = 135/240 = 9/16
H = 12/11 x 7/8 = (12x7)/11x2x4) = 84/88 = 21/22
J = 9/4 x 8/15 = (9x8)/(4x3x5) = 72/60 = 6/5
K = 16/3 x 6/24 = (16x6)/(3x3x8) = 96/72 = 4/3

Voilà
E = [tex]\frac{3}{10}[/tex]
F = [tex]\frac{2*5*3}{3*5*4}[/tex] = [tex]\frac{2}{4}[/tex]
H = [tex]\frac{3*4*7}{11*4*2}[/tex] = [tex]\frac{21}{22}[/tex]
J = [tex]\frac{3*3*4*2}{4*5*3}[/tex] = [tex]\frac{6}{5}[/tex]
G = [tex]\frac{5*3*3*3}{3*2*5*8}[/tex] = [tex]\frac{6}{16}[/tex]
K = [tex]\frac{3*3*4*4}{3*3*2*4}[/tex] = [tex]\frac{4}{2}[/tex] = [tex]\frac{2}{1}[/tex]
