bjr qui peux me résoudre ce petite exercice je vous en prie merci ​

bjr

2/11 - 5/22 = 4-5/22 = - 1/22

10/22 * 33/5 = 5*2/11*2 * 11*3/5 = 1 * 3 = 3

7/4(1/5+3/7) = 7/4 * (1*7/7*5 + 3*5/7*5 ) = 7/4 * 22/35= 22/20 = 11/10

Réponse :

H = -1/22

I = 3

J = 11/10

Explications étape par étape

Bonjour

Calculer :

H = 2/11 - 5/22

H = (2 x 2)/(11 x 2) - 5/22

H = 4/22 - 5/22

H = (-1/22)

I = 10/22 x 33/5

I = 33/22 x 10/5

I = (3 x 11)/(2 x 11) x (2 x 5)/5

I = 3/2 x 2

I = 2/2 x 3

I = 3

J = 7/4 x (1/5 + 3/7)

J = 7/4 x [(1 x 7)/(5 x 7) + (3 x 5)/(7 x 5)]

J = 7/4 x (7/35 + 15/35)

J = 7/4 x 22/35

J = 22/4 x 7/35

J = (2 x 11)/(2 x 2) x 7/(7 x 5)

J = 11/2 x 1/5

J = 11/(2 x 5)

J = 11/10
