Answer 1

Răspuns:

a) nu inteleg ce semn este dupa 3,25..

b)402,35+222,74:0,4=

= 402,35+556,85

=959,2

c)59+6,71•(15-2,45)=

=59+6,71•12,55=

=59+84,2105

=143,2105

d)30+(26,2-0,16):1,23=

=30+26,04:1,23=

=30+21,1707317073

=51,1707317073

e)10:(12,4-12,3)-28,376=

=10:0,1-28,376=

= 100-28,376

= 71,624

f) (3,5:0,5+1,2)•2-1=

=(7+1,2)•2-1=

=8,2•2-1=

=16,4-1=
