What dose scaling mean? Whats the defiition?
Step-by-step explanation: Scaling (For geometry), a linear transformation that enlarges or diminishes objects. Scale invariance, a feature of objects or laws that do not change if scales of length, energy, or other variables are multiplied by a common factor. Scaling law, a law that describes the scale invariance found in many natural phenomena.

Please check the explanation.
Step-by-step explanation:
'3 meals a day' is a unit rate because there is a 1 in the denominator.
A unit ratio is a fraction between two dissimilar units with a denominator 1.
'3 meals a day' indicate that someone is eating 3 meals in one day.
i.e. unit rate = 3 meals / per day
Therefore, we conclude that '3 meals a day' is a unit rate because there is a 1 in the denominator.
The unchanging value of the ratio between the two proportional quantities is called a constant of proportionality.
For example,
we know that the equation
where is the constant of proportionality and '' and '' are two proportional quantities, directly proportional to each other.
Thus, The unchanging value of the ratio between two proportional quantities is called the constant of proportionality.
