Question

Oblicz:

(-7/12) + 3/8 =

1 i 1/6 - (-2 i 1/12) =

4 i 4/7 + 5,4 + (-1 i 4/7) + (-7,4) =

(-0,75) + 6,3 + (-1,1) + (-1/4) + (-6,3) =

3,3 + 6 i 1/7 =

1,6 + 6 i 1/7 =

3,3 +(-6 i 1/7) =

1,6 + (-6 i 1/7) =

3,3 + 1 i 1/13 =

1,6 +1 i 1/13 =

3,3 + (-1 i 1/13) =

1,6 + (-1 i 1/13) =

Proszę, pomóżcie!

Answer 1

[-7/12]+3/8=[-0,58]+0,375= -0,205
1 1/6-[-2 1/12]=7/6-[-25/12]=14/12-[-25/12]=39/12=3 3/12=3 1/4
4 4/7+5,4+[-1 4/7]+[-7,4]=4,57+5.4+[-1,57]+[-7,4]=1
[-0,75]+6,3+[-1.1]+[-1/4]+[-6,3]=[-0,75]+6,3+[-1,1]+[-0,25]+[-6,3]= -2,1
3,3+6 1/7=3,3+6,14=9,44
1,6+6 1/7=1,6+6,14=7,74
3,3+[-6 1/7]=3,3+[-6,14]= -2,84
1,6+[-6 1/7]=1,6+[-6,14]= -4,54
3,3+1 1/13=3,3+1,07=4,37
1,6+1 1/13=1,6+1,07=2,67
3,3+[-1 1/13]=3,3+[-1,07]=2,23
1,6+[-1 1/13]=1,6+[-1,07]=0,53
