Answer:
The constant of proportionality is the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.
Step-by-step explanation:
We call the ratio between two directly proportional quantities the constant of proportionality. When two quantities are directly proportional, they increase and decrease at the same rate. While these two quantities may increase or decrease, the constant of proportionality always remains the same.

First you need to find the total amount of trees by adding up all of the different trees:
420+160+300=880
Next you need to divide the amount of oak trees by the amount of trees in the woods:
160÷880=0.182 (rounded)
Finally to find the precentage we need to multiply the 0.182 by 100 to get the precentage of 18.2% oak trees.
