No. 5000 of most things (other than .005 metres) is not equal to 25 metres.
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.
By the property of uniqueness, number 25 is 25 and only 25, no other number.
