how did this happen? that componendo_dividendo stuff ?
Answers
Answer:
Componendo-Dividendo or componendo and dividendo is a rule that we use to compare and study ratios and proportions. In the following section, we will state this rule and also see some examples that will help us use this method to solve the questions from this section. Let us see.
Step-by-step explanation:
Componendo-Dividendo
Componendo and dividendo is a theorem on proportions that allows for a quick way to perform calculations and reduce the number of expansions needed. It is particularly useful when dealing with equations involving fractions or rational functions in mathematical Olympiads, especially when you see fractions.
Hence, if the ratio of any two numbers is equal to the ratio of another two numbers, then the ratios of the sum of numerator and denominator to the difference of numerator and denominator of both rational numbers are equal. First, let us start by defining some important terms.
