prosze obliczenia -.- daje naj ;p

Answer 1

a) -7/8 : (-5,6) =-7/8* -6/5=42/40

b) 9/10 : (-3/4) =9/10* -4/3=36/30=-6/5

c) (-1 i 1/2) : (- 0,06)=-1,5/ -0,06=25

d) (-2 i 2/3) : 1,2 =-8/3*10/12=-80/36

e) 2/3 : (-6)=2/3* -1/6=-2/18=-1/9

f) (-0,45) : 1 i 4/5=-0,45/1,8=0,25

g) (-2,75) : (-2,2)=1,25

h) (-3,5) : (-1 i 2/5)=-3,5/-1,4=2,5

 

licze na naj:)

Answer 2

a)-7/8:(-56/10)=-7/8*(-10/56)=5/32

b)9/10*(-4/3)=-6/5

c)-3/2*(-100/6)=25

d)-8/3:12/10=-8/3*10/12=-20/9

e)2/3*(-1/6)=-1/9

f)-45/100:9/5=-45/100*5/9=-1/4

g)-275/100:(-22/10)=-275/100*(-10/22)=275/220=1.25

h)-35/10:(-7/5)=-35/10*(-5/7)=25/10=2.5
