15/17 : 2/51 = 15/17 * 51/2 = 15/1 * 3/2 = 45/2 = 22. 1/2

3)

2 : 3/8 = 2 * 8/3 = 16/3 =

5. 1/3

4)

5 : 9/10 = 5 * 10/9 = 50/9 = 5. 5/9

5)

12/13 : 1. 4/5 = 12/13 : 9/5 = 12/13 * 5/9 = 4/13 * 5/3 = 20/39

6)

8/11 : 5. 6/7 = 8/11 : 41/7 = 8/11 * 7/41 = 56/451

7)

23. 1/2 : 5/6 = 47/2 : 5/6 = 47/2 * 6/5 = 47/1 * 3/5 = 141/5 = 28. 1/5

8)

3. 4/7 : 6. 2/3 = 25/7 : 20/3 = 25/7 * 3/20 = 5/7 * 3/4 = 15/28

9)

4. 2/5 : 5. 3/8 = 22/5 : 43/8 = 22/5 * 8/43 = 176/215

10)

3. 11/12 : 2. 9/10 = 47/12 : 29/10 = 47/12 * 10/29 = 47/6 * 5/29 = 235/174 = 1. 61/174
