Question

вычислите; 1) 48+(-62)+37+(-28)+(-3); 2)-2,43+3,51+(-4,5)+1,68+0,22; 3) 14/33+(-37/65)+(-25/33)+24/65

Answer 1

1) 48+(-62)+37+(-28)+(-3)=48-62+37-28-3=-8

2)-2,43+3,51+(-4,5)+1,68+0,22=-2.43+3.51-4.5+1.68+0.22=-1.52

3) 14/33+(-37/65)+(-25/33)+24/65=14/33-25/33+24/65-37/65=-11/33-13/65=-1/3-13/65=-65/195-39/195=-104/195=-8/15
