Sagot :
5 cl = 0.05 l
8 minutes = 2 x 4 minutes = 2 x 0.05 l = 0.10 l
2 mn = 4 minute / 2 = 0.05 l / 2 = 0.025 l
10 mn = 2.5 x 4 minutes = 2.5 x 0.05 l = 0.125 l
24 mn = 6 x 4 minutes = 6 x 0.05 l = 0.25 l
1 mn = 4 minutes / 4 = 0.05 l / 4 = 0.0125 l
39 mn = (10 x 4 minutes) - (4 minutes/4 ) = (10 x 0.05 l) - (0.05 l / 4) = 0.5 l - 0.0125 l = 0.4875 l
Un litre = 1 l / 0.05 = 20 ( 20 correspond au nombre de fois que 4 minute se repete soit 20 x 4 = 80 minutes au total )
J'espere t'avoir aider
Je suis pas sur :s
8 mn = 8.75 cl = 0,0875L
2mn = 2.50 cl = 0.025L
10mn= 12.50cl = 0,125L
24mn = 30cl = 0,3L
1m = 1.25 = 0,0125L
39mn = 48.75cl = 0,4875L
100 centilitres = 1 litres .
