Bonsoir,
L = -4/3 × 5/7 + ⅓
L = -20/21 + ⅓
L = -20/21 + 7/21
L = -13/21
M = 3/5 - 4/3 ÷ 10/7
M = 3/5 - 4/3 × 7/10
M = 3/5 - 28/30
M = 18/30 - 28/30
M = -10/30
M = -⅓
N = 6/(-7/-4)
N = 6×(-4/-7)
N = -24/7
N = -24/7
P = (9/5)/8
P = 9/5 × 1/8
P = 9/40
R = (-5/-4) / (2/-3)
R = 5/4 × (-3/2)
R = -15/8
S = (-5/2 - 8/3) / (4/3 - 5/12)
S = (-15/6 - 16/6) / (16/12 - 5/12)
S = (-31/6) / (11/12)
S = (-31/6) × 12/11
S = -372/66
S = -62/11
T = (1- 4/3) × (2-7/4)
T = (3/3 - 4/3) × (8/4 - 7/4)
T = -⅓ × ¼
T = -1/12
