Sagot :
Bonjour,
230 mn × 76/100 = 174,8 mn
= (2 × 60 + 54) mn + (0,8 × 60) s
= 2 h 54 mn 48 s
4 h × 5/6 = 3,33333.... h
= 3 h + 1/3 h
= 3 h + (1/3 × 60) mn
= 3 h 20 mn
3 h + 1/3 h = 3 h + (1/3 × 60) mn = 3 h 20 mn
Bonjour
76% de 230 min
(76*230)/100 =>174,8mn
5/6 de 4h
4h = 240mn
(240*5)/6 =>200 mn
= 3h 20mn
3h + 1/3h
3h +60/3 => 3h20mn
