Façon 1 :
A = (-15/35 + 28/35) x 35/26
A = 13/35 x 35/26
A = 13 / 26 = 1/2
B= (-9/12 + 8/12 + 24/12) x (-12/15)
B = 23/12 x -12/15
B = -23 / 15
C = -6 x (4/3 - 4,8/3)
C = -6 x -0,8/3 = 2,3/3
D = 0,3 x ( -0,24/0,3 + 2,1/0,3- 3/0,3+ 0,6/0,3)
D = 0,3 x -1,8
D = -0,54
Façon 2 :
A = (-15/35 + 28/35) x 35/26
A = 35/26 x -15/35 + 35/26 x 28/35
A = -15/26 + 28/26
A = 13/26
A = 1/2
B= (-9/12 + 8/12 + 24/12) x (-12/15)
B = -9/12 x -12/15 + 8/12 x -12/15 + 24/12 x -12/15
B = -9/15 + 8/15 + 24/15
B = -23 / 15
C = -6 x (4/3 - 4,8/3)
C = -6 x 4/3 + 6 x 4.8/3
C = -24/3 + 28,8/3 = 4,8 / 3
D = 0,3 x ( -0,24/0,3 + 2,1/0,3- 3/0,3+ 0,6/0,3)
D = 0,3 x -0,24/0,3 + 0,3 x 2,1/3 - 0,3 x 3/0,3 + 0,3 x 0,6/0,3
D = -0,24 + 2,1 - 3 + 0,6
D = -0,54
