Answer 1

3:1 1/2=2  10:3 1/3= 3,3333333   1/2:3/4=3/8   tyle tylko na razie wiem

 

     

Answer 2

3 : 1 1/2 = 3/1 : 3/2 = 3/1 · 2/3 = 6/3 = 2

 

10 : 3 1/3 = 10/1 : 10/3 = 10/1 · 3/10 = 30/10 = 3

 

1/2 : 3/4 = 1/2 · 4/3 = 4/6 = 2/3

 

4/5 : 6/7 = 4/5 · 7/6 = 28/30 = 14/15

 

5/8 : 3/10 = 5/8 · 10/3 = 50/24 = 2 2/24 = 2 1/12

 

4/9 : 5/6 = 4/9 · 6/5 = 24/45

 

5/7 : 1 2/5 = 5/7 : 7/5 = 5/7 · 5/7 = 25/49

 

2 2/5 : 4/9 = 12/5 : 4/9 = 12/5 · 9/4 = 108/20 = 5 8/20 = 5 2/5

 

3/4 : 1 1/8 = 3/4 : 9/8 = 3/4 · 8/9 = 24/36 = 6/9 = 2/3

 

4 2/3 : 7/8 = 14/3 · 8/7 = 112/21 = 5 7/21 = 5 1/3

 

1 1/2 : 1 1/5 = 3/2 : 6/5 = 3/2 · 5/6 = 15/12 = 1 3/12 = 1 1/4

 

1 2/3 : 1 1/9 = 5/3 : 10/9 = 5/3 · 9/10 = 45/30 = 1 15/30 = 1 1/2

 

2 3/4 : 2 1/5 = 11/4 : 11/5 = 11/4 · 5/11 = 55/44 = 1 11/44 = 1 1/4

 

3 1/8 : 3 3/4 = 25/8 : 15/4 = 25/8 · 4/15 = 100/120 = 10/12 = 5/6
