Answer 1

 1) 2 2//3=8//3
(8//3)*(9//32)=0.75
5 1//3=16//3
0.75*(16//3)=4

2) 4 2//5=22//5
 22//5=4.4
 4.4*(15//77)=(6//7)
 7//20=0.35
 (6//7)*0.35=0.3

3)  18//25=0.72
0.72*(10//27)=(4//15)
7 1//2=15//2
15//2=7.5
(4//15)*7.5=2

4) 5 2//5=27//5
27//5=5.4
5.4*(40//81)=(8//3)
(8//3)*(15//16)=2.5

5) 6 1//4=25//4
1 1//35=36//35
25//4=6.25
6.25*(36//35)=(45//7)
2 1//3=7//3
(45//7)*(7//3)=15

6) 12 6//7=90//7
2//25=0.08
(90//7)*0.08=(36//35)
(36//35)*(7//18)=0.4

7)  1 13//27=40//27
 (15//16)*(40//27)=(25//18)
2 4//25=54//25
 54//25=2.16
 (25//18)*2.16=3

8)  3 9//10=39//10
 39//10=3.9
 3.9*(8//13)=2.4
4 1//6=25//6
 2.4*(25//6)=10

9) 8 1//3=25//3
 2 1//5=11//5
 11//5=2.2
 (25//3)*2.2=(55//3)
1 1//11=12//11
 (55//3)*(12//11)=20
