Answer:

16. 6:N = 8:12

8N = 6 × 12

8N = 72

8N/8 = 72/8

N = 9

17. N:7 = 6:21

21N = 7 × 6

21N = 42

21N/21 = 42/21

N = 2

18. 6:N = 3:5

3N = 6 × 5

3N = 30

3N/3 = 30/3

N = 10

19. 3:8 = 6:N

3N = 8 × 6

3N = 48

3N/3 = 48/3

N = 16

20. 2:7 = N:21

7N = 21 × 2

7N = 42

7N/7 = 42/7

N = 6

21. N:9 = 8:3

3N = 9 × 8

3N = 72

3N/3 = 72/3

N = 24

22. N:4 = 15:12

12N = 15 × 4

12N = 60

12N/12 = 60/12

N = 5

23. 4:6 = N:18

6N = 18 × 4

6N = 72

6N/6 = 72/6

N = 12

24. 4:12 = 1:N

4N = 12 × 1

4N = 12

4N/4 = 12/4

N = 3

25. 5:10 = 2:N

5N = 10 × 2

5N = 20

5N/5 = 20/5

N = 4
