Fraction Faut simplifier aidez moi svp!! 17/2 - 5/6= 24/5 + 3/20= 0.5 + 9/7= 1/2 + 1/4 + 1/8 =

17/2 - 5/6
= 17 x 3 / 2 x 3 - 5/6
= 51/6 - 5/6
= 46/6
= 2 x 23 / 2 x 2
= 23/2

24/5 + 3/20
= 24 x 4 / 5 x 4 + 3/20
= 96/20 + 3/20
= 99/20

0.5 + 9/7
= 0,5 x 7 / 1 x 7 + 9/7
= 3,5/7 + 9/7
= 12,5/7

1/2 + 1/4 + 1/8 
= 1 x 4 / 2 x 4 + 1 x 2 / 4 x 2 + 1/8
= 4/8 + 2/8 + 1/8
= 7/8
