2/3 - 1/2=4/6-3/6=1/6
(1/6)/(1/3)=1/6*3=1/2
b) (5/2-5/3) : 6=(15/6-10/6):6=5/6*1/6=5/36

2/3 - 1/2
Sprowadzamy do wspólnego mianownika czyli:
5/6-3/6
-------------
4/6 - 3/6
= 2/6
-------
1/6
= 2/6 : 1/6= 2/6 *6/1=12/6=2
b.
0,6
----------
(5/2-5/3) : 6
0,6
-------
(15/5-10/6):6
= 0,6
----------
5/6 :6
0,6: 1/6 = 6/10 ; 1/6= 6/10 * 6/1 = 36/10= 3,6
