Bonjour
Énoncé : calcule puis donne le résultat sous la forme d'une fractions simplifier.
L = 64/33 x 77/72
L = 64/72 x 77/33
L = (8 x 8)/(8 x 9) x (11 x 7)/(11 x 3)
L = 8/9 x 7/3
L = (8 x 7)/(9 x 3)
L = 56/27
M = 45/49 x 35/54
M = 45/54 x 35/49
M = (9 x 5)/(9 x 6) x (7 x 5)/(7 x 7)
M = 5/6 x 5/7
M = (5 x 5)/(6 x 7)
M = 25/42
N = 55/48 x 15/22
N = 55/22 x 15/48
N = (5 x 11)/(2 x 11) x 15/48
N = 5/2 x 15/48
N = 5/2 x (5 x 3)/(16 x 3)
N = 5/2 x 5/16
N = (5 x 5)/(2 x 16)
N = 25/32
P = 39/-24 x 18/65
P = -39/65 x 18/24
P = -39/65 x (3 x 6)/(4 x 6)
P = -39/65 x 3/4
P = -(13 x 3)/(13 x 5) x 3/4
P = -3/5 x 3/4
P = -(3 x 3)/(5 x 4)
P = -9/20
R = 63/25 x 40/81
R = 63/81 x 40/25
R = (9 x 7)/(9 x 9) x (5 x 8)/(5 x 5)
R = 7/9 x 8/5
R = (7 x 8)/(9 x 5)
R = 56/45
S = 8/21 x 27/16
S = 8/16 x 27/21
S = 8/(2 x 8) x (3 x 9)/(3 x 7)
S = 1/2 x 9/7
S = 9/(2 x 7)
S = 9/14
