Question

UŁAMKI ! PILNE ! NA JUTRO ! A... (5/6 + 1/3) : (2 i 2/3 - 1,75) =

B... 1 i 1/2 : [(1 i 1/4 : 1 i 2/3 ) : 1 i 1/5] =

C... 17/40-0,2 D... ( 3 i 3/5 - 2) razy 5 E... 4 i 3/8

_________ _________________ ______

1 i 3/5 0,04 (1i5/8-0,75)

Answer 1

(5/6+1/3):(2 2/3-1,75)=(15/18+6/18):(8/3-7/4)=21/18:(32/12-21/12)=21/18:11/12=21/18*11/1214/11=1 3/11

1 1/2:[(1 1/4:1 2/3):1 1/5]=1 1/2:[(5/4*3/5):6/5=3/2:(3/4*5/6)=3/2*24/15=12/5=2 2/5

 

17/40-0,2

1 3/5        =9/40*8/5=18/50=0,36

(3 3/5-2)*5        1 1/5*5 

0,04              =   0,04    =6/ 0,04=300/2=150

 

4 3/8                        35/8-7/8=28/8=3 1/2

(1 5/8- 0,75)=
