Zad.1.
(6/14+1 i 5/7) :10=(6/14+ 1 i 10/14) : 10= 1 i 16/14 : 10 = 2 i 1/7 * 10/1 = 15/7 * 10/1 = 150/7 = 21 i 3/7

zad.2.
3 i ¾ - 5 * 3/25 = 3 i ¾ - 3/5 = 3 15/20 - 12/20 = 3 i 3/20

licze na naj !

(6/14+1 5/7):10=(6/14+1 10/14):10=1 16/14 :10= 2 2/14 :10= 3/14

3 3/4 - 5*3/25 = 3 3/4 - 3/5 = 3 15/20 - 12/20= 3 3/20
