All fractions are proportional to some other fraction.
If each side of the equation is a fraction, then it is a proportion.
the same as a unit rate just in fraction form
To determine if 3.20 is proportional to 8, we can compare their ratio to a constant. We can express this as a fraction: 3.20/8, which simplifies to 0.4. If two quantities are proportional, their ratios will remain constant when scaled. In this case, 3.20 is not directly proportional to 8 unless we define a specific context or relationship that connects them.
If it passes through the origin
It means that someone does not know what they are talking about: 3 is not a fraction!
If each side of the equation is a fraction, then it is a proportion.
Proportional reasoning relies on ratios. A key idea is that every ratio can be written as a fraction, and every fraction can be thought of as a ratio. Example: I make just 2/3 as much as my husband – this is thinking about it as a fraction.

if somthing is proportional is will either be Multiplying or Diving
Any non-zero number.

If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.

It has "1" for the numerator.
The average kinetic energy of gas is directly proportional to the temperature. So at 40K, the fraction of the average kinetic energy of hydrogen gas compared to that at 100K would be (40K)/(100K) = 0.4 or 40%.
