C) (3,6+5,55)×0,12+(3-0,12):36
D)0,344×0,0105
E) 0,0342:1,2

Answer 1

a=2,74
b=43.176,69
c=0,08784
d=0,003612
e=0,0285

Answer 2

A) 4 - 3 × 0,42 = 4 - 1,26 = 2,74

B) 432.1196×100 - 527:100 - 0.03×1000=

= 432.1196 × 100 - 527/100 - 0.03×1000

= 43211.96 - (527/100) - 30

= - 527/100 + 43181.96

=-5.27+43181.96

= 43176.69

C) (3,6+5,55)×0,12+(3-0,12):36=

=(3.6+5.55)×0.12+(3-0.12)/36

=(3.6+5.55)×0.12 = 1.098

=(3-0.12)/36=(2.88)/36=0.08

=1.098+0.08=

=1.178

D)0,344×0,0105 = 0,003612

E) 0,0342:1,2 = 0,0285
