Răspuns:

Explicație pas cu pas:

A) in secunde 5 min 30 min 1 asupra 4 min 3 asupra 2 min 1 h

5 min = 300 s

30 min = 1800 s

1/4 min = 60 : 4 = 15 s

3/2 min = 3x60:2 = 90 s

1 h = 60 min = 3600 s

B) in minute 1 asupra 2h 1 asupra 3 h 1 asupra 12 h 2 asupra 5 h 2 asupra 5 h 2 asupra 5 h 5 asupra 6 h 3 asupra 20 h

1/2 h = 60 : 2 = 30 min

1/3 h = 60 : 3 = 20 min

1/12 h  = 60 : 12 = 5 min

2/5 h = 60 x 2 : 5 = 24 min

5/6 h = 60 x5 : 6 = 50 min

3/20 h = 60x3:20 = 9 min

C) in ore 3600 min 483840 min 5 zile 1 saptamana

3600 min = 1 h

483840 : 60 = 8064 h

5 x 24 = 120 h

1 saptamana = 7 zile = 7 x 24 h = 168 h
