Szczegółowe wyjaśnienie:
Zaczynam od samej góry :
0,2 + 2/5 = 2/10 + 2/5 = 1/5 + 2/5 = 3/5
3/5 : 3/4 = 3/5 * 4/3 = 12/15 = 4/5
4/5 - 0,5 = 8/10 - 5/10 = 3/10
3/10 + 1,2 = 0,3 + 1,2 = 1,5 = 1 i 5/10 = 1 i 1/2
1 1/2 * 2 2/5 = 3/2 * 12/5 = 36/10 = 3 i 6/10 = 3 i 3/5
3 i 3/5 : 0,09 = 3 i 6/10 : 0,09 = 3,6 : 0,09 = 360 : 9 = 40
40 - 38,8 = 1,2 = 1 i 2/10 = 1 i 1/5
1 1/5 : 3,6 = 6/5 : 36/10 = 6/5 * 10/36 = 60/180 = 1/3
1/3 + 2 1/6 = 2/6 + 2 i 1/6 = 2 i 3/6 = 2 i 1/2
2 1/2 * 2/25 = 5/2 * 2/25 = 10/50 = 1/5 = 0,2
