4,35 - 3/200 = 4,35 - 0,015 = 4,335
7/8 - 0,78 = 0,875 - 0,78 = 0,095
5,4 - 5/4 = 5,44 - 1,125 = 4,315
4,8 - 1 i 1/3 = 4 i 8/10 - 1 i 1/3 = 4 i 24/30 - 1 i 10/30 = 3 i 14/30 = 3 i 7/15
33,3 + 1/3 - 1,25 = 33 i 3/10 + 1/3 - 1 i 1/4 = 33 i 9/30 + 10/30 - 1 i 1/4 = 43 i 19/30 - 1 i 1/4 = 43 i 38/60 - 1 i 15/60 = 43 i 23/60
2,25 - 1 i 1/3 - 1,5 = 2 i 1/4 - 1 i 1/3 - 1 i 1/2 = 2 i 3/12 - 1 i 4/12 - 1 i 6/12 = 1 i 15/12 - 1 i 4/12 - 1 i 6/12 = 11/12 - 18/12 = -7/12
37,04 - 45,128 = -8,088
6,13 * (-21,2) = -129,956
-216,64 : 0,04 = -5416
