Bonjour
Donner le résultats sous forme fractionnaire :
A: 6/10 + 5/100.
A = (6 x 10) / (10 x 10) + 5/100
A = 60/100 + 5/100
A = 65/100
A = (5 x 13) / (5 x 20)
A = 13/20
B: 2/5 - 1/25.
B = (2 x 5) / (5 x 5) - 1/25
B = 10/25 - 1/25
B = 9/25
C: 23/110 + 4/11.
C = 23/110 + (4 x 10) / (11 x 10)
C = 23/100 + 40/110
C = 63/110
D: 1/3 - 11/18.
D = (1 x 6) / (3 x 6) - 11/18
D = 6/18 - 11/18
D = - 5/18.
