Zad.1
a) 5/6*3/5=1/2
2/9*6/7=4/21
(3/4)² = 9/16
b) 4/9*1/2=2/9
4/5*1/2=2/5
(3/7)² = 9/49
c) 1/4*3/7=3/28
3/5*5/8=3/8
(2/3)³=8/27

zad.2
a) 1 4/9*12 = 13/9*12=52/3=17 1/3
6*2 1/2 = 6*5/2 = 15
2 3/8*12=19/8*12=57/2=28,5
(1 1/4)² = (5/4)² = 25/16 = 1 9/16
(1 1/4)³ = (5/4)³ = 125/64 = 1 61/64
b) 4 2/7*3 1/2 = 29/7*7/2 = 29/2=14,5
8 1/3*2 2/5 = 25/3*18/5 = 20
4 1/5*2 1/7=21/5*15/7 = 9
(1 2/3)³ = (5/3)³ = 125/27 = 4 17/27
(2 1/2)² = (5/2)² = 25/4 = 6,25
