= 2 i 8/12 + 1 i 9/12=
= 3 i 17/12=
= 4 i 5/12
2 i 2/3 : 2/5 =
= 8/3 * 5/2=
= 4/3 * 5/1=
= 20/3=
= 6 i 2/3
2 i 2/3 * 6/7 =
= 8/3 * 6/7=
= 8/1 * 2/7 =
= 16/7 =
= 2 i 2/7
2 i 2/3 : 8 =
= 8/3 * 1/8=
= 1/3 * 1/1 =
= 1/3
2 i 2/3 * 5=
= 8/3 * 5=
= 40/3=
= 13 i 1/3
2 i 2/3 - 1 i 4/5=
= 2 i 10/15 - 1 i 12/15=
= 1 i 25/15 - 1 i 12/15=
= 13/15
