na jutro :ccc bardzo prosze o obliczenia :c

Answer 1

-6  i 3/8 + ( - 1,55 ) =

 

= - 6 i 375/1000 - 1,55=

 

= - 6,375 - 1,55=

 

= - 7,925

 

 

 

 

 

 

 -(-8,8)- 5  i 1/6= 

 

= 8 i 8/10 - 5 i 1/6=

 

= 8 i 24/30 - 5 i 5/30 =

 

= 3 i 19/30

 

 

 

 

 

1,25 + ( -2 i 7/12)=

 

= 1 i 25/100 - 2 i 7/12=

 

= 1 i 1/4 - 2 i 7/12=

 

= 1 i 3/12 - 2 i 7/12=

 

= - 1 i 4/12
