Final answer:
The proportional relationship between one and six is represented by the ratio 1:6, meaning one quantity is six times larger or smaller than the other in a directly proportional situation.
Step-by-step explanation:
The proportional relationship between one and six can be understood as the ratio 1:6 or 1/6.
When we talk about proportion, we are referring to the comparison of two ratios that are found to be equivalent. In the given scenario, if there is a direct proportionality between two quantities and one of them is six times more than the other, then the ratio 1:6 represents this relationship.
For example, if you have one apple and someone else has six apples, the ratio of your apples to theirs is 1:6.
