-36+(-14)+(-25)= -36-14-25= -75
-8 7/15+(-4 1/3)+(-2.2)= -12 12/15 -2 2/10 = -14 30/30 = -15
32+(-48)+20= -16+20=4
-4 5/14+3 5/7+(-2,8)= 1/14 - 2 8/10= 5/70 -2 56/70= -2 51/70
1) 5,(3) = 5 3/9 = 5 1/3 и 2,(6) = 2 6/9 = 2 2/3 и 5 1/3 + 2 2/3 = 8
или 5,(3)+2,(6) = 7,(9) = 8 - ОТВЕТ
2) 7 4/9 - 3 1/9 = 4 1/3 - ОТВЕТ
3) 9 4/9 + 4 5/9 = 14 - ОТВЕТ
4) 6,(23) = 6 23/99, 3,(6) = 3 6/9 = 3 66/99
6 23/99 - 3 66/99 = 2 56/99 - ОТВЕТ
