Answer 1

2/3×3/4=6/12=1/2

3/4:1/8=3/4×8/1=24/4=6

6/7×3/4=18/24=9/12=3/4

7/16:1cala i 1/6=7/16:7/6=7/16×6/7=1/16×6=6/16=3/8

Answer 2

2/3 * 3/4 = 1/2
3/4 : 1/8 = 3/4 * 8/1 = 6
1 2/9 : 1 5/6 = 11/9 : 11/6 = 11/9 * 6/11 = 2/3
5/12 * 1 7/15 = 5/12 * 22/15 = 11/18
2 2/5 : 1 8/15 = 1 13/23
1 9/16 * 8/25 = 1/2
7/16 : 1 1/6 = 3/8
