1) Le deuxième payre 10/7 * 14/30 = 2/3
2) 14/30 + 2/3 = 34/30 = 17/15; L'addition etait de 15/15
3) 2/15
2) 14/30 + 2/3 = 34/30 = 17/15; L'addition etait de 15/15
3) 2/15
1) p=10/7*14/30
=140/210
=14/21
=2/3
2) 14/30+2/3
=14/30+20/30
=34/30 > 1
3) p=34/30-1
=34/30-30/30
=4/30
=2/15
=140/210
=14/21
=2/3
2) 14/30+2/3
=14/30+20/30
=34/30 > 1
3) p=34/30-1
=34/30-30/30
=4/30
=2/15
