8,25 + 3,3 = 11,55
36/10 * 1/6 (6 skruci sie z 36) = 6/10 = 3/5
2 i 2/3 - 2/10 = 2 i 20/30 - 6/30 = 2 i 14/30 = 2 i 7/15
72/10 : 8/5 = 72/10 * 5/8 (odwracamy ułamek) = 9/2 = 4 i 1/2
1/2 * 1/2 + 2/10 * 6/5 = 1/4 + 6/25 = 0,25 + 0,24 = 0,49
5,4 : ( 38/7 - 38/10) = 5,4 : (380/70 - 266/70) = 5,4 : 114/70 = 5,4 : 1 i 44/70 =
=54/10 * 70/144 = 27/1 * 7/72 = 3 * 7/8 = 21/8 = 2 i 5/8
prosze o naj :)
