bonjour
Explications étape par étape :
A=5/10+74/100
=50/100 +74/100
=124/100
=31x4 / 25x4
=31/25
B=4/5+3/10
=8/10 +3/10
=11/10
C=3/2 +7/6
=9/6+7/6
=16/6
=2x8/3x2
=8/3
D= 3/16-5/8
=3/16 - 10/16
=-7/16
E= 15/21 +2/3
=15/21 + 14/21
=29/21
F=-5/21 + 3/7
=-5/21 + 9/7
=4/7
A = 50/100 + 74/100 = 124/100 ( j ai mis tout au même dénominateur pour pouvoir additionner )
B= 8/10 + 3/10 = 11/10
C= 9/6+7/6 = 16/6
D = 3/16 + -10/16 = -7/16
E = 15/21 + 14/21 = 19/21
F = -5/21 + 9/21 = 4/21
B= 8/10 + 3/10 = 11/10
C= 9/6+7/6 = 16/6
D = 3/16 + -10/16 = -7/16
E = 15/21 + 14/21 = 19/21
F = -5/21 + 9/21 = 4/21
