Answer 1

There are infinitely many ways to adjust two quantities so that they are in a given proportional relationship.

To understand why, let's consider an example. Let's say we have two quantities, A and B, and we want them to be in a proportional relationship such that A is twice the value of B.

One way to adjust the quantities to meet this requirement is to start with any value for B and then multiply it by 2 to get the corresponding value for A. For instance, if we choose B = 4, then A = 2 * 4 = 8. Similarly, if we choose B = 10, then A = 2 * 10 = 20.

But that's not the only way. We can also choose A and then divide it by 2 to get the corresponding value for B. For example, if we choose A = 6, then B = 6 / 2 = 3. Similarly, if we choose A = 18, then B = 18 / 2 = 9.

We can see that regardless of the value we pick for one quantity, we can always adjust the other quantity accordingly to maintain the given proportional relationship. This means there are infinitely many ways to adjust the quantities to achieve the desired proportional relationship.
