2.77+(-1/4) = 2,77 - 0,25 = 2,521/3+(-1/2) = 2/6 - 3/6 = -1/62 5/12+(-17 3/8) = 2 10/24 - 17 9/24 = -14 23/24-29+17 1/8 = -11 7/817+(-1,25) = 17 - 1,25 = 15,75-2 3/5+(-7 3/10) = -2 6/10 - 7 3/10 = -9 9/104 3/4+(-4 11/12) = 4 9/12 - 4 11/12 = -2/12 = -1/6

2,77-0,25=2,521/3-1/2 = 2/6-3/6= -1/62 5/12 - 17 3/8 = 2 10/24 - 17 9/24= -(16 33/24-2 10/24)= -14 23/24-29 + 17 1/8= -(28 8/8-17 1/8)= -11 7/817-1,25= 15,75-2,6-7,3=-(2,6+7,3)=-9,94 3/4- 4 11/12= 4 9/12-4 11/12 = -(4 11/12-4 9/12 ) = -2/12= -1/6
