Explications étape par étape
A= (11/3-7)/(25/6)
A = (11/3-21/3)/(25/6)
A = (-10/3)/(25/6)
A = -10/3*6/25
A = (-5*2*3*2)/(3*5*5)
A = -4/5
B = (1/3-1/5):2/5
B = (5/15-3/15):2/5
B = 1/15 * 5/2
B = (1*5)/(5*3*2)
B = 1/6
C = 5/4-(9/13*65/81)+11/36
C = 5/4-(9*13*5)/(13*9*9)+11/36
C = 5/4 -5/9 + 11/36
C = 45/36 - 20/36 + 11/36
C = 36/36
C = 1
D = 13/5 * (19/26-2/13)
D = 13/5 * (19/26-4/26)
D = 13/5 * 15/26
D = (13*5*3)/(5*13*2)
D = 3/2
