a)
45 minut - 45/60 = 3/4
25 minut - 25-60 = 5/12
1 sekunda - 1/3600
15 sekund - 15/3600 = 1/240
b)
200 metrów - 200/1000 = 1/5
8 metrów - 8/1000 = 1/125
125 centymetrów = 125/100000 = 1/800
1500 centymetrów - 1500/100000 = 3/200
45 minut - 45/60 = 3/4
25 minut - 25-60 = 5/12
1 sekunda - 1/3600

b)
200 metrów - 200/1000 = 1/5
