What are the means and extremes in proportions?
In a proportion, the means are the two terms that are closest together when the proportion is written with colons. The extremes are the terms in the proportion that are furthest apart when the proportion is written with colons.
What does the means extremes property of proportions State?
The means-extremes property of proportions allows you to cross multiply, taking the product of the means and setting them equal to the product of the extremes. This property comes in handy when you’re trying to solve a proportion.

What is the extreme of a proportion?
EXTREMES: The extremes are the values of the proportion that are furthest apart when written in ratio form using a colon. For example: In the proportion a : b = c : d, ‘a’ and ‘d’ are the extremes. MEANS: The means are the values of the proportions that are the middle terms.
What are the extremes?
In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means. Here, 20 and 5 are the extremes, and 25 and 4 are the means.
What are proportions means and extremes quizlet?
In a true proportion, product of means is equal to product of extremes. Means = middle Extremes = ends.
What is mean by product of extremes?
A proportion is a statement that two ratios are equal. The proportion a/b is read as a is to b as c is to d. The first and last terms (a and d) are called the extremes, and the middle terms (b and c) are called the means. In a proportion, the product of the means equals the product of the extremes.
What is the difference between means and extremes?
As adjectives the difference between mean and extreme is that mean is (obsolete) common; general or mean can be having the mean (see noun below ) as its value while extreme is of a place, the most remote, farthest or outermost.

What rule do equal proportions follow?
The two outer terms. To determine if a proportion is equal, follow this rule: The product of the means is equal to the product of the extremes. In the proportion 2 : 3 :: 4 : 6, the means are 3 and 4.
What are properties of proportions?
Properties of Proportions If two ratios are equal, then their reciprocals must also be equal as long as they exist. The product of the extremes is equal to the product of the means.
