-3/4 + (-3/10) = -15/20 + (- 6/20) = - 21/20= - 1 1/20
-2 5/9 + (- 2 5/8 ) = -2 40/70 + (- 2 45/72) = - 5 13/72
-6 7/12 + 7 4/9 = 7 16/36 - 6 21/36 = 31/36

- 12 3/8 + 4 11/2 = - 12 3/8 + 9 1/2 =
=-12 3/8 + 9 4/8 = -2 7/8
или
-12 3/8 + 41 1/2 = 41 4/8 -12 3/8 = 29 1/8

-3/4+(-3/10) = -(3/4+3/10) = =-(15/20+6/20) = =-21/20=-1целая 1/20

-2целых 5/9+(-2ц.5/8) = -(2 ц.5/9+2ц.5/8) = -(4ц.+(40/72+45/72)) = -4ц. 85/72 = -5ц.13/72

-6ц.7/12+7ц.4/9 = 7ц.4/9-6ц.7/12 = 7ц.16/36 -6ц.21/36 = 31/36
