Aidez moi svp je n y arrive vraiment pas

a) 1/6 x 12 = 12/6 = 2, donc Deux carreaux

b) 1/4 x 12 = 12/4 = 3, donc Trois carreaux
1/3 x 12 = 12/3 = 4, donc Quatre carreaux
1/2 x 12 = 12/2 = 6, donc Six carreaux

c) E tu le places au 11e carreau
F = 5/6 = 5/6 x 12 = 60/60 = 10 carreaux
G = 3/4 = 3/4 x 12 = 36/4 = 9 carreaux
H = 3/2 = 3/2 x 12 = 36/12 = 3 carreaux
