Step-by-step explanation:
1. 30/6 = 15/N
Solution:
30n = 90
30n = 90 n = 90/30
30n = 90 n = 90/30 n = 3
2. 21/3 = 46/N
Solution:
21n = 147
21n = 147 n = 147/21
21n = 147 n = 147/21 n = 7
3. N/9 = 2/3
Solution:
3n = 18
3n = 18 n = 18/3
3n = 18 n = 18/3 n = 6
4. 1/N = 8/16
Solution:
8n = 16
8n = 16 n = 16/8
8n = 16 n = 16/8 n = 2
5. 75/N = 4/8
Solution:
4n = 600
4n = 600 n = 600/4
4n = 600 n = 600/4 n = 150
