Question

calcule los 4/7 de 4 dias 15h 20 minutos

Answer 1

1 hora = 60 minutos
20/60 = 1/3 hora

1 día = 24 horas
4*24 = 96 horas

4 días 15 horas 20 minutos = 96 +15+ 1/3 = 111 1/3 horas
 =  333/3 + 1/3 = 334/3 horas

(334/3)*(4/7) = (334*4)/ (7*3) = 1336/21
1336/21 = 1323/21 + 13/21 = 63 13/21

60*13/21 =  37.14 minutos
0.14*60 =  8.4 segundos

63/24 = 48/24 + 15/24 = 2 15/24
15/24*24 = 15 horas

2 días 15 horas  37 minutos 8.4 segundos
