2 3/4 - 5 =

4 2/3 - 2 11/15 =

-4,3 -9=

-1,09-(-0,9) =

1 5/6 -4,3 =

1,357 - (0,9 - 3/4) =

Answer 1

5,25 + 4i1/3 + 2 i 1/12 = 5 i 1/4  + 4 i1/3 + 2 i1/12= 5 i 3/12 +4 i4/12+2 i1/12=

= 11 i 8/12 = 11 i 2/3

 

2 i 3/4 - 5 = 2 i 3/4 - 4 i 4/4 = - 2 i 1/4

 

4i2/3 -2i 11/15 = 4 i 10/15 - 2 i 11/15= 3 i25/15- 2i 11/15 = 1 i 14/15

 

-4,3 - 9 = - 13,3

 

-1,09 - (-0,9 )=  -1,09 + 0,9 = 1

 

1 i5/6 -4,3 = 1i5/6-4i3/10 = 1i 25/30 - 4i 9/30 = 1i25/30-3i39/30 = -2 i 14/30

 

1,357 - (0,9 -3/4)= 1,357 -(0,9-0,75)= 1,357 -(0,15)= 1,357-0,15= 1,207
