Explications étape par étape

Bonsoir,

Consigne : simplifier, lorsque c'est possible, les fractions suivantes :

A = 6/21

A = (3 * 2)/(3 * 7)

A = 2/7

B = 100/1000

B = 100/(100 * 10)

B = 1/10

C = 76/64

C = (4 * 19)/(4 * 16)

C = 19/16

D = 11/121

D = 11/(11 * 11)

D = 1/11

E = 3⁵/3⁷

E = 3⁽⁵⁻⁷⁾

E = 3⁻²

F = 243x/x

F = (243 * x)/x

F = 243

G = 2x²/(4x^3)

G = 2x²/(2x² * 2x)

G = 1/(2x)

H = 45ab/(15a)

H = (3b * 15a)/(15a)

H = 3b

I = 14/(7x)

I = (2 * 7)/(7 * x)

I = 2/x

J = 35/13 (irréductible)

K = 36x/(8 - 2)

K = 36x/6

K = (6 * 6x)/6

K = 6x

L = (99 - 9)/(23 + 7)

L = 90/30

L = (30 * 3)/30

L = 3

M = [2(x - 1)]/[(x - 1)(x + 2)]

M = 2/(x + 2)

N = (2x + 2)/2

N = 2(x + 1)/2

N = x + 1

O = (2x - 2)/(4x)

O = 2(x - 1)/(2 * 2x)

O = (x - 1)/(2x)
