Question-
What is meant by the product of means = product of extremes?
Answer-
If you are asking the reason, then you should first understand some terms that I am going to use here to explain the answer.
Let us take an example ratio and proportion - 10:5::2:1
As you can see clearly, the numbers are underlined or italicised. The numbers which are underlined, that is 10 and 1, are called extremes. The numbers which are italicised, that is 5 and 2, are called means.
In Ratio and proportion, there is one important relationship between the extremes and means. The product of extremes = The product of means.
