Réponse:
V=3×8/1×8 + 5×4/2×4 + 3×2/4×2
V=24/8 + 20/8 + 6/8
V= 50/8
V= 25/4 (simplifier)
W=2×4/3×4 - 5×3/4×3 - 11/12
W=8/12 - 15/12 - 11/12
W= -18/12
W= -3/2 (simplifier)
Y=1×3/2×3 + 4×2/3×2 - 5/6
Y=3/6 + 8/6 - 5/6
Y= 11/6 - 5/6
Y= 6/6
Y=1 (simplifier)
Z=2×7/1×7 - 6/7 + 3/2
Z=14/7 - 6/7 + 3/2
Z=8/7 + 3/2
Z=8×2/7×2 + 3×7/2×7
Z=16/14 + 21/14
Z= 37/14 (simplifier)
