bonjour

A = 1 - 5 /9  

   = 9 /9 - 5 /9

   = 4 /9

B  = 6/10 + 7

   = 6 /10 + 70/10

   = 76/10

   =   38/5

c = 9/100 + 3 /10

 = 9/100 + 30/100

  = 39/100

D = 7/4 - 4 /12

   =  21/12 - 4/12

  =  17/12

E = 1/48 + 10/8

  = 1/48 + 60/48

  = 61/48

F = 8 - 7/5

  = 40/5 - 7/5

   = 35/5

   = 7

allez fais les derniers

Bonsoir

Explications étape par étape

A = 1 -5/9

A = 1 X 9/9 -5/9

A = 9/9 -5/9

A = 4/9

B = 6/10 +7

B = 6/10 +7 X 10/10

B = 6/10 +70/10

B = 76/10 = 38/5 = 7,6

C = 9/100 +3/10

C = 9/100 + 3/10 X 10/10

C = 9/100 +30/100

C = 39/100

D = 7/4 -4/12

D = 7/4 X 3/3 -4/12

D = 21/12 -4/12

D = 17/12

E = 1/48 +10/8

E = 1/48 +10/8 X 6/6

E = 1/48 + 60/48

E = 61/48

F = 8 -7/5

F = 8 X 5/5 -7/5

F = 40/5 -7/5

F = 33/5

G = 10/5 -1

G = 10/5 -1 X 5/5

G = 10/5 -5/5

G = 5/5 = 1
