Answer 1

5/14*7= 5/14* 7/1= 5/2*1/1= 5/2= 2,5
5/9*6= 5/9*6/1= 5/3*2/1= 10/3= 3 1/3
3/7* 4/5= 12/35
4/9* 3/8= 1/3*1/2= 1/6
3 3/5* 10= 18/5*10/1= 18/1* 2/1= 36/1= 36
2 1/4* 2/3= 9/4* 2/3= 3/2* 1/1= 3/2= 1,5
1 7/8* 2 2/5=  15/8* 12/5= 3/2* 3/1= 9/2= 4,5
3 1/3* 4 4/5= 10/3* 24/5= 2/1* 8/1= 16

3/4: 5/7= 3/4* 7/5= 21/20= 1 1/20
1/3: 4/7= 1/3* 7/4= 7/12
3: 1/6= 3/1* 6/1= 18/1=18
2 1/3: 5/4= 7/3* 4/5= 28/15= 1 13/15
3/10: 2 3/4= 3/10* 4/11= 12/110
2 2/3: 1 7/9= 8/3* 9/16= 1/1* 3/2= 3/2= 1,5

Answer 2

5/14 * 7 = 5/2
5/9 * 6 = 10/3
3/7*4/5 = 12/35
4/9*3/8=1/6
3 3/5 * 10 = 18/5*10=36
2 1/4 * 2/3 = 9/4*2/3=3/2
1 7/8 * 2 2/5 = 15/8*12/5=9/2
3 1/3 * 4 4/5 = 10/3*24/5=16

3/4:5/7=3/4*7/5=21/20
1/3:4/7=1/3*7/4=7/12
3:1/6 = 3*6/1 = 18
2 1/3 : 5/4 = 7/3*4/5=28/15
3/10 : 2 3/4 = 3/10 * 4/11 = 12/110
2 2/3 : 1 7/9 = 8/3*9/16=3/2
