Find the constant of proportionality for the ratio \(\frac{2}{5}\).

The "constant of proportionality" is the value that relates the two amounts Example: you are paid $20 an hour (continued) The constant of proportionality is 20 because: Earnings = 20 × Hours worked
This can be written: y = kx
Where k is the constant of proportionality

The constant of proportionality for the ratio 5 2 ​ is k = 5 2 ​ . This indicates that for every unit increase in one variable, the other variable increases by 5 2 ​ of that unit. This establishes a direct relationship between the two quantities.
