Extended proportion is a concept in mathematics that relates four quantities using ratios. It states that if a/b = c/d, then a/b can be written as a fraction equivalent to x/d, where x is some other quantity that belongs to the same system as a, b, c, and d.
In other words, extended proportion is used to compare three or more quantities using ratios, by finding a missing value in a proportion. It is important in various fields including engineering, physics, and finance.
