-2 1,2 x 1 1/3
- 44,5 : 1 1/3

Proszę o pomoc.

Answer 1

-(5 : 1 i 2/3 + 6 i 1/3)  * 2=

= - (5 : 5/3 + 6 i 1/3) * 2 =

= - (5 * 3/5 + 6 i 1/3) * 2=

= - ( 1 * 3/1 + 6 i 1/3)* 2=

= - ( 3/1 + 6 i 1/3) * 2=

= - 9 i 1/3 * 2=

= - 28/3 * 2=

= - 56/3=

= - 18 i 2/3





- 2,4 +3  i 2/3=

= - 2 i 4/10 + 3 i 20/30=

= - 2 i 12/30 + 3 i 20/30

= 1 i 8/20 =

= 1 i 2/5






-7  i 1/6 - 1,5=

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

= - 7 i 1/6 - 1 i 1/2=

= - 7 i 1/6 - 1 i 3/6=

= - 8 i 4/6=

= - 8 i 2/3






-2 i 1/2  *  1 i 1/3 =

= - 5/2 * 4/3 =

= - 5/1 * 2/3=

= - 10/3=

= - 3 i 1/3




- 44,5 : 1 i 1/3=

= - 44 i 5/10 : 4/3=

= - 44 i 1/2 : 4/3=

= - 89/2 * 3/4 =

= 267/12=

= 22 i 3/12=

= 22 i 1/4
