Bonsoir,
F = 10/3 × 21/5 = 2×5/3 × 3×7/5 = 2 × 7 = 14
G = 3/7 × 2 = 6/7
H = 1/8 × 3/8 = 3/64
I = 14/55 × 22/15 × 9/28 = 2×7/5×11 × 2×11/3×5 × 3×3/2×2×7 = 3
J = 3/5 / 3/7 = 3/5 × 7/3 = 21/15 = 7/5
K = 21/10 / 14/5 = 21/10 × 5/14 = 105/140 = 3×7×5 / 2×5×2×7 = 3/6 = 1/2
L = 12 / 15/2 = 12 × 2/15 = 4×3 × 2/ 3×5 = 8/5
Bonne soirée
