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)
