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
The solution to this equation is x=4.6 because 19.32/4.2=4.6
For example 1ft = 12in so 12 is the number that you are going to multiply so just multiply 25×12 and that is your answer
