20x12 i 1/2=
20:12 i 1/2=
13 i 1/3 + 12=
13 i 1/3- 12=
13 i 1/3 x 12=
13 i 1/3 : 12=
4 i 1/3+2 i 1/2=
4 i 1/3-2 i 1/2=
4 i 1/3 x 2 i 1/2=
4 i 1/3:2 i 1/2=
20+12 i 1/2=

Answer 1

20*12i1/2=20*13/2=130
20:12i1/2=20*2/13=40/13
13i1/3+12=14/3+36/3=50/3=16i2/3
13i1/3-12=14/3-36/3=-22/3=-7i1/3
13i1/3*12=14/3*12=56
13i1/3:12=14/3*1/12=7/18
4i1/3+2i1/2=13/3+5/2=26/6+15/6=41/6=6i5/6
4i1/3-2i1/2=13/3-5/2=26/6-15/6=11/6=1i5/6
4i1/3*2i1/2=13/3*5/2=65/6=10i5/6
4i1/3:2i1/2=13/3*2/5=26/15 (nie ma sensu wyciągać całości )
20+12i1/2=32i1/2
