Two numbers or variables are directly proportional if their ratio is constant.
Put another way, two numbers or variables are directly proportional if one of them is a constant multiple of the other.
a is proportional to b ( a ∝ b ) if
a/b= constant or equivalently a=b x (constant)
When to numbers or variables are directly proportional, if one doubles the other doubles,
if one is halved the other is halved, etc.

In an analogy there be a relationship between the words?
An analogy is when two things have something in common and the relationship can be seen or measured. It also means two things can be compared.

It is quantitative data.
What does the term 'proportional' refer to?
The term "proportional" is used to denote a relationship between two things with respect to their size. In mathematics the meaning is that two quantities have the same or a constant ratio or relation.
What observations include numbers to make them more acerate?
Things that can be measured should be included to make them more accurate.

Explain or what is the meaning of the relationship of the stars brightness and distance?
Other things being equal, the farther the star, the less bright it will seem to us. Specifically, the apparent brightness is inversely proportional to the square of the distance.
What is the definition of proportional relationships?
Directly proportional relationships mean that if one of the related things is multiplied in size by a number, which we'll call x, then the other related thing is also multiplied by x. Inversely proportional relationships mean that if one of the related things is multiplied in size by a number, x, then the other related thing is divided by x (or multiplied by 1/x , the two are equivalent as multiplication and division are commutative, if that's of interest....) Things can also be related by higher order proportionality. If thing P is proportional to the square of Q (a proportionality of order 2) then if Q is multiplied by a number x, P is multiplied by x2. In general though, if two things are in a proportional relationship it means that when one is multiplied by a certain amount, the other is multiplied by a related amount.
