j)(-1,1/2) : (-0,06) =

Zad 3 a) 6+(-4) + (-10) =

-4 - (-9) -3 =

-16 + 7 - 28 =

b) 4,3 - 7,4 + 1,1 =

(-6,2) +1,6 - (-2,3) =

7,8 - 5,4 - 12,1 =

Kto to obliczy dobrze dostaje naj!!

Answer 1

a)(-100)*8/25=-100/1*8/25=-32

b) 1 2/3*(-6 2/3=5/3*(-32/5)= -32/3=-10 2/3

c) (- 2 2/5)*(-3 3/4)= - 12/5*(-15/4)=9

d)(-9,45)*0.28=-2.676

e)0.04*(-0.27)=4/100*(-27/100)=-27/2500

f)(-3,6)*4/9= -3 3/5* 4/9=-18/5*4/9= - 1 3/5

g)(-2.1)*(-4 2/7)=-21/10*(-30/7)=9

 h) (-1 1/2) : (-0.06)=-3/2*100/6=25

 

 

 

 a)6+(-4)+(-10)=6-4-10=-8

b)-4-(-9)-3=-4+9-3=2

c)-16+7-28=-37

 d)4.3-7.4+1.1=-2

e)(-6.2)+1.6-(-2.3)=-6.2+1.6+2.3=-2.3

f)7.8-5,4-12.1=2.4-12.1=-9.7 

Answer 2

a) = -32

b) = - 32/3= - 10 i 2/3

c) = 9

d) = -2,6460

f) = - 1 i 27/45

g) = 9

j) = -25

 

zad.3

a) -8

=2

=- 37

b) = -2

= -2,3

= - 9,7
