What Is the Definition of Extremes in Math? When solving proportions in math, the outer terms in the calculation are the extremes, and the middle terms are called the means. When setting the proportion equation a/b = c/d, the a and the d figures are the extremes.

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.

First if you have a proportion (two equal fractions) like [math]\frac{a}{b}=\frac{c}{d}[/math] then the means are b and c and the extremes are a and d. Now the Means Extremes property is that you can cross multiply like this ad = bc and the equality still holds.

The two middle numbers are the means, and the two outer numbers are the extremes. To make sense of the term cross-multiply, though, you should write this proportion using fraction notation: So, we can cross-multiply the means (1 × 120) and the extremes (60 × 2) and see that the respective products are equal (1 × 120 = 120, and 60 × 2 = 120).

Product of extremes = 3 × 12 = 36 and product of means = 4 × 9 = 36 (vii) From the terms of a given proportion, we can make three more proportions. (viii) If x : y = y : z, then x, y, z are said to be continued proportion.
