Question

101,3 + (84,7 + 1,11); (47,28 - 34,98) + (55,02 + 34,98); (46,83 + 15,77) - (6,83 - 5,77). все это по действиям, в столбик.

Answer 1

101,3+(84,7+1,11)=101,3+85,81=187,11

(47,28-34,98)+(55,02+34,98)=12,3+90=102,3

(46,83+15,77)-
(6,83-5,77)=62,6-1,06=61,54

       62.60   (46.83 + 15.77)
    -    1.06   (6.83 - 5.77)
    ________
       61.54

So, the solutions are:

1. 101.3 + (84.7 + 1.11) = 188.91
2. (47.28 - 34.98) + (55.02 + 34.98) = 102.30
3. (46.83 + 15.77) - (6.83 - 5.77) = 61.54
