Question

Which pair of ratios will make a proportion ?

Answer 1

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.
