Answer 2

Ответ:

1: -43+(60)+18+367(-19)= -6.938

2: -2,43+6,31+(-3,21)+0,49+4,87= 6.03

3: 19/43+(-9/16)+(11/42)+5/16= -0.429

Answer 3

Let's solve each of these mathematical expressions step by step:

1. -43 + (60) + 18 + 367(-19):

   -43 + 60 + 18 + 367 * (-19) = -43 + 60 + 18 - 6973 = -6937

2. -2.43 + 6.31 + (-3.21) + 0.49 + 4.87:

   -2.43 + 6.31 - 3.21 + 0.49 + 4.87 = 5.03

3. -19/43 + (-9/16) + (11/42) + 5/16:

   To add these fractions, it's helpful to find a common denominator, which in this case is 672.

   -19/43 * (16/16) + (-9/16) * (42/42) + (11/42) * (32/32) + 5/16 * (42/42) =

   -304/672 - 378/672 + 352/672 + 210/672

   Now, add these fractions:

   (-304 - 378 + 352 + 210) / 672 = (-120) / 672 = -5/28

So, the answers are:

1. -6937
2. 5.03
3. -5/28
