effectuer les calculs suivants:

A = 1/3 × - 4/5

B = (2, 2)/5 × - 3/5

C = - 10/3 × - 5/7

D = - 8/3 × 3/4 × 5/7

E = 2/15 × - 13/7

F = - 1, 2 × 3/25

G = 7/8 × (- 3) × 5/4

H = 2/3 × - 3/2 × 1/2​

Bonjour :)

Réponse en explications étape par étape :

- Question : Effectuer les calculs suivants :

A = 1/3 * - 4/5

A = - 4/15

B = (2, 2)/5 * - 3/5

B = - 6,6/25

B = (- 6,6 * 5)/(5 * 5)

B = - 33/125

C = - 10/3 * - 5/7

C = 50/21

D = - 8/3 * 3/4 * 5/7

D = - 24/12 * 5/7

D = - 120/84

D = - (12 * 10)/(12 * 7)

D = - 10/7

E = 2/15 * - 13/7

E = - 26/105

F = - 1,2 * 3/25

F = - 3,6/25

F = - (3,6 * 5)/(25 * 5)

F = - 18/125

G = 7/8 * (- 3) * 5/4

G = - 21/8 * 5/4

G = - 105/32

H = 2/3 * - 3/2 * 1/2​

H = - 6/6 * 1/2

H = - 1 * 1/2

H = - 1/2

Voilà
