Ответ:
17 + (-11 + 5.4) = 17 - 5.6 = 11.4
(14.2 - 5) - (12.2 - 5) = 9.2 - 7.2 = 2
15 + (-12 + 4.5) = 15 - 7.5 = 7.5
(-2.8 + 15) - (-5.6 + 2.8) + (2.8 - 15) = 12.2 - (-2.8) + (-12.2) = -2.8
32.3 - (5.3 - 4.7) = 32.3 - 0.6 = 31.7
1) 17+(-11+5,4)=17+(-5,6)=17-5,6=11,4;
2) (14,2-5)-(12,2-5)=9,2-7,2=2;
3) 15+(-12+4,5)=15+(-7,5)=15-7,5=7,5
4) (-2,8+15)-(-5,6+2,8)+(2,8-15)=12,2-(-2,8)+(-12,2)=
=12,2+2,8+(-12,2)=2,8
5) 32,3-(5,3-4,7)=32,3-0,6=31,7
готово :)
