ration
the first and fourth terms of a proportion are called the means ?
A statement that two ratios are equal is called a proportion in math. An example of a proportion is 1/2 equals 2/4. In this proportion, if you cross multiply, you find that 4 x1 is equal to 2 x 2, which is a true statement or proportion.
Their circumferences are in direct proportion to their radii. Their areas are in direct proportion to the square of their radii.

Actually, the terms located in the middle of a proportion are called the means. The first and fourth terms are the extremes.

The two outer terms of a proportion are known as extremes. These are the limits of a range of possibilities.
In a proportion, the two outer terms are the first and last terms in the ratio. For example, in the proportion ( \frac{a}{b} = \frac{c}{d} ), the outer terms are ( a ) and ( d ). The relationship between these terms is that the product of the outer terms is equal to the product of the inner terms, which can be expressed as ( a \times d = b \times c ).

this is the outermost terms this is ''extremes''
In a proportion, the means are the middle terms, and the extremes are the outer terms. Given the means are 6 and 18, and the extremes are 9 and 12, the proportion can be expressed as ( \frac{9}{12} = \frac{6}{18} ). Simplifying both sides, ( \frac{9}{12} ) reduces to ( \frac{3}{4} ), and ( \frac{6}{18} ) reduces to ( \frac{1}{3} ), indicating that these values do not form a valid proportion.
The first and last terms of a proportion are called the "extremes." In a proportion expressed as ( a:b = c:d ), ( a ) and ( d ) are the extremes, while ( b ) and ( c ) are referred to as the "means." This terminology helps in understanding relationships between the terms in a proportion.
The two outer terms of a proportion are the first term on the left-hand side and the last term on the right-hand side. These terms are usually compared to determine if they are in the same relationship as the two inner terms.
In a proportion, which is an equation that states two ratios are equal, the second and third terms refer to the values involved in the ratios. For example, in the proportion ( a:b = c:d ), ( b ) is the second term and ( c ) is the third term. These terms are crucial for solving proportional equations, as they help determine the relationship between the quantities involved.
