Answer 1

1. 3,24+5,07-(1,5-0,7)=3,24+5,07-0,8=8,31-0,8=7,51.

2. 0,23+11,07+17+24,35=11,3+17+24,35=28,3+24,35=52,65

3. a=21,37-19,03=2,34

b=0,123+124,51=124,633

a+b=2,34+124,633=126,973

b-a=124,633-2,34=122,293~~122,3

4. a=57-43,2+1,04=13,8+1,04=14,84

a-b=14,84-2,2=12,64

5. a) 137,54×100=13754

b) 837,4×3,72=3115,128

c) 3,4³=39,304
