Step-by-step explanation:
Answer:
14:6
21:9
28:12
Step-by-step explanation:
Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:
7 x 2 = 14
3 x 2 = 6
14:6
7 x 3 = 21
3 x 3 = 9
21:9
7 x 4 = 28
3 x 4 = 12
28:12
(X * 6) + 9 = 8
6x + 9 = 8
6x + 9(-9) = 8(-9)
6x = -1
6x/6 = -1/6
x = -1/6
