Zad.1
a) 2*3/4 = 3/4 + 3/4 = 6/4 = 1 2/4 = 1 1/2
b) 3*2/5 = 2/5 + 2/5 + 2/5 = 6/5 = 1 1/5
c) 2*2 1/4 = 2 1/4 + 2 1/4 = 4 2/4 = 4 1/2
d) 3*1 2/5 = 1 2/5 + 1 2/5 + 1 2/5 = 3 6/5 = 4 1/5
Zad.2
a) 2*2/3 = 2/3 + 2/3 = 4/3 = 1 1/3
b) 3*1/2 = 1/2 + 1/2 + 1/2 = 3/2 = 1 1/2
c) 3*2/4 = 2/4 + 2/4 + 2/4 = 6/4 = 1 2/4 = 1 1/2
d) 2*7/10 = 7/10 + 7/10 = 14/10 = 1 4/10 = 1 2/5
e) 3*4/6 = 4/6 + 4/6 + 4/6 = 12/6 = 2
f) 3*1/3 = 1/3 + 1/3 + 1/3 = 3/3 = 1
