Answer 1

Пошаговое объяснение:

1) 602,432:8-(653,8:7-170,5:5) =

= 75,304-(93,4-34,1) = 75,304-59,3=16,004

2) 674,268:7+(387,063:9-2,82:6) =

=96,324+(43,007-0,47)=96,324+42,537=

= 138,861

3) 34,5*9-75,6:8+451,392:6 =

= 310,5-9,45+75,232 = 376,282

4) 408,12+4-96,21:3+284,9:7 =

= 412,12-32,07+40,7 = 420,75

5) 80,14:2-6,456:8+480,18:6-0,19*5 =

= 40,07-0,807+80,03-0,95 = 118,343
