Answer 1

(-56,3)+(-0,9);(-38)+34+2,5;26/3-33/12-(-8/3)-9/2;

1*(-56,3)+(-0,9);
1) -56,3+(-0,9)= -56,3-0,9= 56,3+0,9= -57,2

2*(-38)+34+2,5;
1) -38+34=38-34= -4
2) - 4+2,5= 4 - 2,5= -1,5

3*26/3-33/12-(-8/3)-9/2
1) 3×26/3= 26
2) 26-33/22= 26/100-3/2= -24/100= -6/25
3) -6/25-(-8/3)= -6/25+8/3= 8/3-6/25= 182/75
4) 182/75-9/2= -311/150= 2целые 11/150
