A proportion is an equation with a ratio on each side. It is a mathematical statement expressing equality between two races.
3/4 = 6/8 is an example of a proportion.
When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number. This is called solving the proportion. Question marks or letters are frequently used in place of the unknown number.
Proportional Representation (PR) describes various multi-winner voting systems which try to ensure that the proportional support gained by different groups is accurately reflected in the election result.
However, district or constituency borders may be gerrymandered to create "majority-minority" districts or constituencies where a group of voters in the minority system-wide form the majority in a particular district or constituency, thus allowing a simulation of proportionality system-wide.
Proportional representation is unfamiliar to most citizens of the United States, but it is actually a much more common system of voting than first-past-the-post.
Proportional representation (PR) is any election system which ensures a proportionally representative result of a democratic election, x% of votes should be represented by x% in the democratic institutions, parliament or congress.
In general, first-past-the-post is only used in former British colonies, but a form of proportional representation known as the mixed member system is now being used in the United Kingdom to elect the members of the Scottish Parliament and the Welsh National Assembly.
Although once an unknown system, proportional representation is now gaining popularity in Canada with five provinces: British Columbia, Ontario, Quebec, Prince Edward Island and New Brunswick currently debating whether to abolish the first past the post system, and at the federal level, a Parliamentary Committee is now exploring the issue.
