Answer 3

7/12:1/9= 7/12 * 9/1 = 63/12 = 5  3/12 = 5  1/4

 

9/10:3= 9/10 * 1/3 = 9/30 = 3/10

 

7,2:5= 7  1/5 : 5 = 36/5 * 1/5 = 36/25 = 1  11/25

 

0,6:1 1/7= 3/5 : 8/7 = 3/5 * 7/8 = 21/40

 

2:3,5= 2 : 3  1/2 = 2 : 7/2 = 2 * 2/7 = 4/7

 

6 2/9:13,5= 6  2/9 : 13  1/2 = 56/9 : 27/2 = 56/9 * 2/27 = 112/243
