Answer 1

25,8+4,5x2,3-5,15x4,2=271,068

 

6,3x1,2-2,5x0,2+3,8x1,05=5,0526

 

10,6x5,8-26,38-7,5x4,26=117,576

 

(17,8+2,48)x5,05-13,85x4,2=371,9688

 

2,75+34,25x(57,6-7,6x7,5)=13875

 

72,3-2,05x(6,03x5,4-30,062)=175,65

Answer 2

a) 25,8 + 4,5 * 2,3 - 5,15 * 4,2=

=25,8 + 10,35 - 21, 630=

=36,15 - 21, 630=

=14,520

b) 6,3 * 1,2 - 2,5 * 0,2 + 3,8 * 1,05=

=7,56 - 0,50 + 3, 990=

=7,06 + 3, 990=

=11, 050

c) 10,6 * 5,8 - 26,38 - 7,5 * 4, 26=

=61,48 - 26, 38 - 31, 950=

=35, 10 - 31, 950=

=3,150

d) (17,8 + 2, 48) * 5,05 - 13,85 * 4,2=

=10, 28 * 5,05 - 13,85 * 4,2=

=101,9140 - 58,170=

=43, 7440

e)2,75 + 34, 25 * (57,6 - 7,6 * 7,5)=

=2,75 + 34, 25 * (57,6 - 57, 00)=

=2,75 + 34, 25 * 00,60=

=2,75 + 020, 7500=

=023, 5000

f) 72,3 - 2,05 * (6,03 * 5,4 - 30,062)=

=72,3 - 2,05 * (32,662 - 30,062)=

=72,3 - 2,05 * 2,600=

=72,3 - 5,33005=

=66, 96995

 

Mam nadzieję, że pomogłam ;)
