Hello there! An answer to your question could be 2/3.
A proportional relationship relationship has to have the same value as the original fraction. One way we can find a proportional relationship is by simplifying this given fraction, since it just makes the numbers smaller and doesn't change the value.
To simplify this equation, you need to find a number that is divisible by both numbers in the fraction, in this case it's 24 and 36. You can divide both numbers by 1, 2, 3, 4, 6 and 12. Since the question is asking you to find a proportional relationship and not straight up simplify, you can use any of these (except for 1, which won't make a difference). I'm going to use 12, since it's easiest.
Again, to simplify, just divide both of the numbers in the fraction. In this case we are dividing 24 and 36 by 12.
24 ÷ 12 = 2
36 ÷ 12 = 3
So 24/36 = 2/3. These two fractions have a proportional relationship. If you want to verify that, just divide the numerator by the denominator and if they get the same value, they are in fact proportional.
24 ÷ 36= 0.66666666666...
2 ÷ 3 = 0.66666666666....
So, they are in fact proportional. I hope I could help you today and have a great rest of your day! ☺
