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.

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.
Well, honey, the external terms of a ratio are the first and last numbers in the ratio, while the internal terms are the second and third numbers. So if you've got a ratio like 2:5, the external terms are 2 and 5, and the internal terms are... you guessed it... 2 and 5. Math can be a real hoot, can't it?
The cross product is created.
7/35 = 5/x You have a proportion here. A proportion is a statement that two ratios are equal. The numbers that form a proportion are called the terms of proportion. There is a special relationship between the terms, called the cross products property. In the proportion that you have, 7 and x are called the extremes of the proportion, and 35 and 5 are called the means. In a proportion, the product of the means equals to the product of the extremes. So, 7/35 = 5/x (7)(x) = (35)(5) 7x = 175 7x/7 = 175/7 x = 25 Thus 7 is to 35 as 5 is to 25.
A trinomial is an expression that consist of three terms (first term, middle term, and last term). The middle term is the sum of the product of outer terms and inner terms of the binomial.
