0,4 h .......min

2/3 h .......min

9,6 h.........min

1/6 h.........min

24 min.........h

40 min........h

60 min..... .h

10 min........h

Answer 1

0,4 h = 4/10 * 60min = 240/10 min = 24min

2/3 h  = 2/3 * 60min = 120/3 min = 40min

9,6 h = 96/10 * 60min = 96 * 6 = 576 min

1/6 h = 1/6 * 60min = 60/6 min = 10min

24 min = 24 : 60 h = 24/60 h = 4/10 = 0,4h

40 min = 40/60 h = 4/6 h = 2/3h

60 min = 60 : 60 = 60/60 = 1h

10 min = 10 : 60 h= 10/60h = 1/6.h
