Question

PILNIE POTRZEBUJE ODPOWIEDZI NA TE ZADANIA, DAJE NAPRAWDĘ DUŻO PUNKTÓW. BŁAGAM O POMOC. ;(((((((((

TYLKO DOBRZE ZRÓBCIE

Answer 1

(5/6+1/3):(2 2/3-1,75)=(5/6+2/6):(8/3-1 3/4)=7/6:(8/3-7/4)=7/6:(64/24-42/24)=7/6:22/24=7/6*24/22=28/22=14/11=1 3/11

 

1,6+4 3/5:2,3-2 2/5=1,6+ 23/5:23/10-2,4=1,6+2-2,4=3,6-2,4=1,2

 

(-0,8+(-12):2 2/5)+3/8(-1,6)=(-0,8+(-12/1):12/5)+3/8*(-16/10)=(-0,8+(-5))+(-0,6)=-5,8-0,6=-6,4

 

(-4+2/3:0,2):(1,6:(5:2-4 1/2))=(-4+2/3:2/10):(16/10:(2 1/2-4 1/2))=(-4+2/3*10/2):(16/10:(-2)=(-4+10/3):(16/10*(-1/2)=(-2/3):(-8/10)=(-2/3)*(-10/8)=10/12=5/6

 

 

Answer 2

(5/6+1/3):(2 2/3-1,75)=

(5/6+2/6):(2 2/3-1 3/4)=

7/6:(1 20/12-1 9/12)=

7/6:11/12=

7/6 * 12/11=

14/11=1 3/11

 

1,6+4 3/5:2,3-2 2,5=

1,6+4,6:2,3-2,4=

1,6+2-2,4=

1,2

 

(-0,8+(-12):2 2/5)+3/8*(-1,6)=

(-0,8+(-12):2,4)+0,375*(-1,6)=

-0,8+(-5)+(-0,6)=

-6,4

 

(-4+2/3:0,2) : ((1,6:(5:2-4 1/2)) =

(-4+2/3*2/10):((1,6:(2,5-4,5))=

(-12/3+10/3):((1,6:(-2))=

(-2/3):(-8/10)=

(-2/3)*(-10/8)=

12/10=

5/6
