Bonjour,A = 3/5 + 1/5 x (1/3 - 2/15)
A = 3/5 + 1/5 x (1 x 5 / 3 x 5 - 2/15)
A = 3/5 + 1/5 x (5/15 - 2/15)
A = 3/5 + 1/5 x 3/15
A = 3/5 + 3/75
A = 3 x 15 / 5 x 15 + 3/75
A = 45/75 + 3/75
A = 48/75
A = 3 x 16 / 3 x 25
A = 16/25
B = 3/4 x 2/7
5/6 + 3/2
B = 6/28 ____
5/6 + 3 x 3 / 2 x 3
B = 6/28
5/6 + 9/6
B = 6/28 : 14/6
B = 6/28 x 6/14
B = 36/392
B = 4 x 9 / 4 x 98
B = 9/98
