## Important Topics for Hall and Knight Higher Algebra Solutions Chapter 1: Ratio

**Ratio **

Ratio is a topic that you would have already tackled in your junior classes. In Hall & Knight Algebra Book Chapter 1, you will again encounter some familiar concepts and some new ones. Here, you will revise the basic definition of ratio, which is a relationship that exists between two quantities of the same kind.

The ratio can be explained as the relation which one quantity bears to another one of the similar kind such that it expresses comparison based on multiple, fractions, parts or other. You will also get to know that ratios are abstract quantities as they are an expression of the number of times one quantity is contained in another.

**Antecedent and Consequent **

In this chapter, you will also learn about the terms antecedent and consequent. Taking an example of C : D, which is a representation of the ratio of C to D. Here we can refer to C and D as the terms of the ratio. And amongst these two terms which express a ratio, whichever terms appear first is known as an antecedent and the term which appears second is known as the consequent. The chapter has numerous examples where the use of these terms has been explained and their importance has been emphasized. You will come across many such terms in the chapter and will learn to use them while deriving your solutions.

**Commensurable Ratios and Incommensurable Ratios **

The chapter ‘ratio’ of Higher Algebra by Hall & Knight deals with the terms commensurable ratios and incommensurable ratios. Basically, in case if the given ratios belonging to any two quantities can be exactly expressed by the ratio of any two integers, those quantities are termed as commensurable.

Any quantity which does not follow the given conditions falls in the other category of incommensurable ratios. These terms play a vital role in organizing and deriving answers to the problems discussed in the chapter.

**Rule of Cross Multiplication **

One of the key fundamentals of this chapter is the rule of cross multiplication. This rule is used in order to solve problems that have two different equations containing three variable quantities in their first degrees. The given equations are written in a fractional form and after solving them they are further arranged in a symmetrical manner. The terms of coefficients of the equations are analysed and the respective coefficients of x, y and z are written separately.

These coefficients are then multiplied across and the final product obtained is the answer. This is a very important concept and will be utilized in numerous questions from the unsolved examples. It is also important from the perspective of competitive exams. You will get to understand this concept through the detailed examples that have been listed in the chapter.
