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

Answer 2

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) 
$frac{14}{33}$ - $frac{37}{65}$ - $frac{25}{33}$ + $frac{24}{65}$ = - $frac{11}{33}$ - $frac{13}{65}$ = - $frac{1}{3}$ - $frac{1}{5}$ = - $frac{5}{15}$ - $frac{3}{15}$ = - $frac{8}{15}$
