• Try refreshing and if it doesn't work you can read the transcript.
• its said like this: Bowl-in-yays. its yays.
• can i do this without math
• This is a math problem, so you will have to do some math.
• I don't understand this question. A proportional relationship happens when the ratios that are formed are equal so you have to do the operation by the same number for example if I were multiplying by 2, I would multiply all of the numbers by 2. But in this example, 2 of the pairs were divided by 3 and one was divided by 5. So how come this works?
• You wouldn't need to multiply by the same number, because as long as the ratio is equal, they are proportional. In this example, the ratios for all three pairs is 3:5. As another example, 1/2 is proportional to 5/10 and 7/14. Even though you divide by a different factor, you will always get the same ratio of 1 to 2. Hope this helps!
