Answer:
B. 3/5 and 9/15
Step-by-step explanation:
When looking for a proportion, you must look at a ratio that equals the same like:
1/2 = 2/4
You could see that I would just have to multiply or divide the numbers by 2.
So, that means they doubled.
3/5 = 9/15
How would you get 9 from 3? You would multiply by 3 to get 9.
Therefore, to check if it is a proportion, multiply with the same number you used to multiply the first number, which would be 3.
5 × 3 = 15.
Since 15 is written in the ratio, B would be the correct answer.
Therefore, B is the Correct Answer.
