1/3 : 0,6 + 625 : 100 - 4 i 1/3 - 1/3 * (3,6 - 1 i 2/3) + 2 i 3/4 =
= 1/3 : 3/5 + 6,25 - 4 1/3 - 1/3(3 3/5 - 1 2/3) + 2 3/4 =
= 1/3 * 5/3 + 6,25 - 4 1/3 - 1/3(3 9/15 - 1 10/15) + 2 3/4 =
= 5/9 + 6 1/4 - 4 1/3 - 1/3(2 24/15 - 1 10/15) + 2 3/4 =
= 5/9 + 9 - 4 1/3 - 1/3 * 1 14/15 = 9 5/9 - 4 3/9 - 1/3 * 29/15 = 5 2/9 - 29/45 =
= 5 10/45 - 29/45 = 4 55/45 - 29/45 = 4 26/45
