Oblicz:
5 i 2/9 - 1 i 1/6
__________________=
3 i 2/3 x (1 i 1/4 - 1/2)
(47/9 - 7/6)/[11/3 * (5/4-2/4)] = (94/18 - 21/18)/ (11/3 * 3/4) = 73/18 * 4/11 = 146/99
5 2/9- 1 1/6 do wspólnego mianowniak mnożymy 9*2 a 6*3
___________
3 2/3 *(1 1/4- 1/2)
5 i 4/18 - 1 i 3/ 18
_______________
3 2/3 * 3/4
4 i 1/18
________
11/3 * 3/4
11/4
73/18 * 4/11 = 146/99=1 i 47/99
