Prosze pomóżcie :( :( :( ( nie piszcie od razu wyników)

Answer 1

- 3 i 5/7 - 6 i 7/8 =

= - 3 i 40/56 - 6 i 49/56=

= - 9 i 89/56=

= - 10 i 33/56



10 i 3/5 - 11 i 5/7 =

= 10 i 21/35 - 11 i 25/35=

= - 1 i 2/35




-8 i 4/9 - 13 i 5/6=

= - 8 i 16/36 - 13 i 30/36=

= - 21 i 46/36=

= - 22 i 10/36=

= - 22 i 5/18




-6 i 1/4 - (-3 i 3/8)=

= - 6 i 2/8 + 3 i 3/8=

= - 2 i 7/8




-7 i 5/6 - ( - 10 i 1/7)=

= - 7 i 35/42 + 10 i 6/42=

= 2 i 13/42




-0,7-1 i 3/4=

= - 0,7 - 1 i 75/100=

= - 0,7 - 1,75=

= - 2,45




7,23-(-3 i 1/2)=

= 7,23 + 3 i 5/10 =

= 7,23 + 3,5=

= 10,73





6 i 5/8 - (- 7,3)=

= 6 i 625/1000 + 7,3=

= 6,625 + 7,3=

= 13,925





-2 i 1/4 - (- 6,105)=

= - 2 i 25/100 + 6,105 =

= - 2,25 + 6,105=

= 3,855





-8,39-(-12 i 1/8)=

= - 8,39 + 12 i 125/1000 =

= - 8,39 + 12,125=

= 3,735





-12,11 - (- 13,09)=

= - 12,11 + 13,09=

= 0,98




-6,34- 5 i 4/5=

= - 6,34 - 5 i 8/10 =

= - 6,34 - 5,8=

= - 12,14





-9,14 - (- 6 i 7/20)=

= - 9,14 + 6 i 35/100 =

= - 9,14 + 6,35=

= - 2,79





10 i 4/7 - (-2,1)=

= 10 i 4/7 + 2 i 1/10 =

= 10 i 40/70 + 2 i 7/70 =

= 12 i 42/70 =

= 12 i 3/5




-6 i 1/3 - (-4,8)=

= - 6 i 1/3 + 4 i 8/10 =

= - 6 i 1/3 + 4 i 4/5 =

= - 6 i 5/15 + 4 i 12/15=

= - 1 i 8/15





18,6 - (-20 i 7/25)=

= 18,6 + 20 i 28/100 =

= 18,6 + 20,28=

= 38,88




- 16,102 + 5,94= - 10,162



13,12 - ( - 2 i 1/3)=

= 13 i 12/100 + 2 i 1/3=

= 13 i 3/25 + 2 i 1/3=

= 13 i 9/75 + 2 i 25/75 =

= 15 i 34/75




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

= - 2,5 - 3 i 25/100 =

= - 2,5 - 3,25 =

= - 5,75




0,7 + (-2,6)=

= 0,7 - 2,6=

= - 1,9
