in the proportion, a/b = c/d, a and d are the extremes. from the def in my math book

EXTREMES
The two outer terms of a proportion are known as extremes. These are the limits of a range of possibilities.
The numerator of the second ratio and the denominator of the first ratio are called the means, and the numerator of the first ratio and the denominator of the second ratio are called the extremes. The product of the means equals the product of the extremes.

meansThe two outside one are the extremes.
6/9 = 10/15
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.
the first or the last term of a proportion or series. a relative maximum or relative minimum value of a function in a given region.
One standard way is it use colons , For example 7:14::6:12 read as 7 is to 14 as 6 is to 12. The number in the middle are called the means; those on either end are called the extremes. In a correct proportion, the product of the means equals the product of the extremes. In the example, note that 7 times 12 = 14 times 6.
