Szczegółowe wyjaśnienie:
2,8 = 2 8/10 = 20/10 + 8/10 = 28/10 = 28:2/10:2 =
= 14/5 = 10/5 + 4/5 = 2 + 4/5 = 2 4/5
-7,004 = - 7 - 4/1000 = - 7 - 4:4//1000:4 = - 7 - 1/250 = - 7 1/250
-83,08 = - 83 - 8/100 = - 83 - 8:4/100:4 = - 83 - 2/25 = - 83 2/25
6,14 = 6 + 14/100 = 6 + 14:2/100:2 = 6 + 7/50 = 6 7/50
9,05 = 9 + 5/100 = 9 + 5:5/100:5 = 9 1/20
-13,002 = - 13 - 2/1000 = - 13 - 2:2/1000:2 = - 13 1/500
-12,75 = - 12 - 75/100 = - 12 - 75:25/100:25 = - 12 3/4
15,06 = 15 + 6/100 = 15 + 6:2/100:2 = 15 3/50
