1 : 3/4 = 1 · 4/3 = 4/3 = 1 i 1/3
4/3 : 3/4 = 4/3 · 4/3 = 16/9 = 1 i 7/9
1/3 : 3/4 = 1/3 · 4/3 = 4/9
1 · 3/4 = 3/4
4/3 · 3/4 = 1
1/3 · 3/4 = 1/4
6 : 3/4 = 6 · 4/3 = 8
7/4 : 3/4 = 7/4 · 4/3 = 7/3 = 2 i 1/3
5/8 : 3/4 = 5/8 · 4/3 = 5/6
zad 5
3/4 : 2/7 = 3/4 * 7/2 = 21/8
3/5 : 1/3 = 3/5 * 3/1 = 9/5
4/5 : 5/3 = 4/5 * 3/5 = 12/25
4/5 : 5/4 = 4/5 * 4/5 = 16/25
