C'est pour mon cousin s'il vous plaît merci.

Bonsoir,

1/6 + 2/6 = 3/6 = 1/3

1/20 + 5/20 = 6/20 = 3/10

2/20 -1/20 =  1/20

2/18 + 1/18 = 3/18 = 1/6

2/16 - 1/16 = 1/16

2/14 +1/14 = 3/14

2/10-1/10= 1/10

1/3 +1/3 = 2/3

2/8 -1/8 = 1/8

Le bonjour au cousin!

Bonsoir,

Simplifier :

1/6 + 1/3 = 1/6 + 1×2/3×2 = 1/6 + 2/6 = 3/6 = 1/3

1/20 + 1/4 = 1/20 + 1×5/4×5 = 1/20 + 5/20 = 6/20 = 3/10

1/10 - 1/20 = 1×2/10×2 - 1/20 = 2/20 - 1/20 = 1/20

1/9 + 1/18 = 1×2/9×2 + 1/18 = 2/18 + 1/18 = 3/18 = 1/6

1/8 - 1/16 = 1×2/8×2 - 1/16 = 2/16 - 1/16 = 1/16

1/7 + 1/14 = 1×2/7×2 + 1/14 = 2/14 + 1/14 = 3/14

1/5 - 1/10 = 1×2/5×2 - 1/10 = 2/10 - 1/10 = 1/10

1/3 + 1/3 = 2/3

1/4 - 1/8 = 1×2/4×2 - 1/8 = 2/8 - 1/8 = 1/8

✅️

/ = fraction

Bonne soirée
