sauf exercice 1et2 sinon le 3 il faut le faire svp aider moi c pour demain

T = 2/5 + 5/3 = 2×3/5×3 + 5×5/3×5 = 6/15 + 25/15 = 31/15

U = 1/15 + 1/3 = 1×3/15×3 + 1×15/3×15 = 3/45 + 15/45 = 18/45

V = 24/56 + 13/7 = 24×7/56×7 + 13×56/7×56 = 168/392 + 728/392 = 896/392

W = 4/3 + 15/4 = 4×4/3×4 + 15×3/4×3 = 16/12 + 45/12 = 61/12

X = 3/12 + 7/16 = 3×16/12×16 + 7×12/16×12 = 48/192 + 84/192 = 142/192

Y = 5/6 + 2/3 + 13/9 = 5×3/6×3 + 2×6/3×6 + 13×2/9×2 = 15/18 + 12/18 + 26/18 = 53/18

Z = 4/3 + 7/12 + 14/8 = 4×8/3×8 + 7×2/12×2 + 14×3/8×3 = 32/24 + 14/24 + 42/24 = 88/24
