Пошаговое объяснение:
1) 1 3/4+ (-1/2)=1 3/4 - 2/4=1 1/4
2) 5 2/9 + (-1/3)= 5 2/9 - 3/9=4 8/9
3) 4 3/8 + (-1/4)= 4 3/8 - 2/4=4 1/8
4) 5 1/2 + (-8 5/6) = 5 3/6 - 8 5/6= -3 2/6= -3 1/3
5) 4 1/3+ (-7 5/9)= 4 3/9 - 7 5/9= -3 2/9
6) 3 3/8 + (-9 1/2)= 3 3/8 - 9 4/8= -6 1/8
7) 2 1/3 + (-4 5/6) = 2 2/6- 4 5/6= -2 3/6= -2 1/2
8) 1 1/12 + (-5 1/6)=1 1/12- 5 2/12= -4 1/12
9) 3 2/15 + (-9 1/3) = 3 2/15 - 9 5/15= -6 3/15= -6 1/5
