Bonjour,
Retrouver la contenance de chaque format :
3/10 + 7/100 + 5/1000
= (3 x 100)/(10 x 100) + (7 x 10)/(100 x 10) + 5/1000
= 300/1000 + 70/1000 + 5/1000
= 375/1000
= 0,375 L
= 37,5 cL
1 + 1/2
= (1 x 2)/(1 x 2) + 1/2
= 2/2 + 1/2
= 3/2
= 1,5 L
25/100
= 0,25 L
= 25 cL
75/100
= 0,75 L
= 75 cL
2/10
= 0,2 L
= 20 cL
20 cL => Piccolo
25 cL => Chopine
37,5 cL => Fillette
75 cL => bouteille
1,5 L => magnum
