Odpowiedź :
2/3 + 0,5 : 3 = 20/30+ 15/30: 3 = 35/30: 3/1 = 35/30* 1/3=35/90
0,2+ 5/6 = 2/10+ 5/6 = 6/30+ 25/30 = 31/30
35/90: 31/30 = 35/90* 30/31 = 35/3* 1/31= 35/93
Odpowiedź:
2/3 + 0,5 : 3 2/3 + 1/2 : 3 2/3 + 1/2 * 1/3 2/3 + 1/6
--------------------- = --------------------- = --------------------- = ---------------- =
0,2 + 5/6 2/10 + 5/6 6/30 + 25/30 31/30
4/6 + 1/6 5/6
-------------- = ---------- = 5/6 : 31/30 = 5/6 * 30/31 = 5/1 * 5/31 = 25/31
31/30 31/30
--------
