svp aidez moi il faut effectuer les calculs et le résultat correspond au coupable ​

A = 2/9 + 5/9
A = 7/9 (Mme Dubuc)

B= -4/3 - 6/3
B = -10/3 (Mme Chastan)

C = 12/5 + 3/5
C = 15/5
= 3 (M. Dos Reis)

D= 18/3 + 1
= 18/3 + 3/3
= 21/3
= 7 (Mr Carrerot)

E = 1/3 + 5/6
= (1x2)/(3x2) + 5/6
= 2/6 + 5/6
= 7/6 (Mme Konczewki)

F = 5/14 - 11/7
= 5/14 - (11x2)/(7x2)
= 5/14 - 22/14
= -17/14 (Yasmine)

G = 3/2 + 5/10
= (3x5)/(2x5) + 5/10
= 15/10 + 5/10
= 20/10
= 2 (M. Mhoundi)

H = 1/6 + 2/10
= (1x10)/(6x10) + (2x6)/(10x6)
= 10/60 + 12/60
= 22/60
= 11/30 (Nour l’Imane)

I = 7/18 -2/3
= 7/18 - (2x6)/(3x6)
= 7/18 - 12/18
= -5/18 (Mme Issartial)


Il reste donc M. Miraillet, qu’est donc le suspect.
