Explications étape par étape :
exo 1
a) 7/6 = 6/6 + 1/6
= 1 + 1/6
b) 15/6 =6/6 + 6/6 + 3/6
= 12/6 + 3/6
= 2 + 1/2
exo 2
a) 20/7= 7/7 + 7/7 + 6/7
= 14/7 + 6/7
= 2 + 6/7
b) 25/12 = 24/12 + 1/12
= 2 + 1/12
Exo 3
7/5 = 5/5 + 2/5
= 1 + 2/5
13/7 = 7/7 + 6/7
= 1 + 6/7
17/8 = 8/8 + 8+8 + 1/8
= 2 + 1/8
18/9= 9/9 + 9/9
= 2
Je te laisse le soin de faire les dessins correspondants a chaque fraction
Bonjour,

( A compléter sous 7/6 : 1 + 1/6
sous 15/6 : 5/2 )
1 /
a) 7/6 = 6/6 + 1/6
= 1 + 1/6
b) 15/6 =6/6 + 6/6 + 3/6
= 12/6 + 3/6
= 2 + 1/2
2/
a) 20/7 = 7/7 + 7/7 + 6/7
= 14/7 + 6/7
= 2 + 6/7
b) 25/12 = 24/12 + 1/12
= 2 + 1/12
3/
7/5 = 5/5 + 2/5
= 1 + 2/5
13/7 = 7/7 + 6/7
= 1 + 6/7
17/8 = 8/8 + 8/8 + 1/8
= 2 + 1/8
18/9= 9/9 + 9 /9
= 1 + 1
= 2
