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
