Bonjour
6/5+2/3
= (6 x 3) / (5 x 3) + (2 x 5) / (3 x 5)
= 18/15 + 10/15
= 28/15
2/3-4/3
= - 2/3
2/3+4/3x15/8
= 2/3 + 60/24
= (2 x 8) / (3 x 8) + 60/24
= 16/24 + 60/24
= 76/24
= (4 x 19) / (4 x 6)
= 19/6.

Explications étape par étape
6/5 +2/3
6/5 X 3/3 +2/3 X 5/5
18/15 +10/15
28/15
2/3 -4/3 = -2/3
2/3 +4/3 X 15/8
2/3 +60/24
2/3 X 8/8 +60/24
16/24 +60/24
76/24 = 38/12 = 19/6
