A mathematical relationship where two variables change in such a way that if one increases or decreases by a certain factor, the other does so by the same factor, resulting in a constant ratio between them.
The concept where two quantities or elements maintain a consistent relative scale to each other, meaning as one quantity rises or falls, the other does so correspondingly, often reflected in practical scenarios such as demographics or physical properties.
In terms of design or aesthetics, the harmonious relationship between parts of an object or a whole, where the sizes or dimensions of components are balanced with each other, contributing to overall visual unity.
Example:
給与が増えるに比例して、所得税率もあがっていく。
A mathematical relationship where two quantities increase or decrease together, maintaining a constant ratio between them throughout the process.
A concept in mathematics emphasizing a specific type of proportional relationship where the ratio remains unchanged regardless of the values of the two related quantities.
The condition in which one quantity varies directly with another, ensuring their relationship remains constant over a range of values.
A form of proportionality characterized by the mutual increase or decrease of two variables while preserving a fixed relationship in terms of their ratio.
A mathematical relationship between two varying quantities where an increase in one results in a proportional decrease in the other, such that the product of the two quantities remains constant.
A scenario in which one quantity increases while the other decreases in a way that their relationship can be represented as the inverse of one another, often described by the equation xy = k, where k is a constant.
A concept describing the interaction of two quantities where as one doubles, the other halves, illustrating a negative correlation where an increase in one leads to a decrease in the other.
A voting system in which parties gain seats in the legislature in proportion to the number of votes they receive, ensuring that smaller parties have representation in governance.
A method of electing representatives that aims to reflect the diversity of voter preferences by distributing seats based on the percentage of votes each party obtains.
A political framework that allows for a more equitable representation of various political views and demographic groups within a governing body, as opposed to winner-takes-all systems.
