The fourth proportion is a mathematical formula that is used to solve many radio-related problems in a short period. This approach is mostly used in the SSC exams where the time for solving these types of questions is very short. This formula helps in the calculation of complex problems easily in a short time. It is mainly used in ratios in the calculation of an unknown quantity. For example, if in a ratio, the value of a, b and c is described, the value of d will easily be found out with the help of the fourth proportion formula. On the other hand, it is very difficult to solve a problem of ratio without the application of the fourth proportional formula in it.
Formulae for Proportion-Fourth Proportional
Let us consider there are four variables such as A, B, C, and D which are in proportion shown below. A: B:: C: D will be the proportion of these variables. In this case, D is called the fourth proportion of variables A, B, and C. For example, let’s consider the value of A, B, and C is given as 5, 10, and 12. Then the value of variable D can be found out with the formulae of the fourth proportion. The formulae for the fourth proportion ratio has been shown below.
The above value can be written as 5:10 :: 12:D
It can also be written as 5/10 = 12/D. The value of D is 24. Hence, the value of the fourth proportionality has easily been determined with the help of the fourth proportional formula in a short time.
Role of Fourth Proportional in mathematics
There is a very important fourth proportion in mathematics. It has been found that many complex problems which are based on Ratios are easily solved with the help of the proportional formulae in a smooth way. It has also been seen that the formula of fourth proportionality has played a very important role in the competitive exams such as SSC, banking, railways, etc. in the SSC exam, the time for solving a problem is very short that is less than a minute given for a problem. It is
Application of Fourth Proportional
There are various types of benefits of the fourth proportional formula in mathematics. This formula is implemented in mathematics to solve various critical problems of ratios in a simplified way. The application of the Fourth proportional formula in different areas has been stated below.
- The fourth proportional formula is used in various mathematical ratio-related problems where three values are given and the value of the fourth variable is required.
- This Proportional formula is also applicable in the solution of questions of SSC exams in a short period. As it is known that one minute is given in the solution for problems of the SSC exam, it is difficult to solve this question without implementing a proportional formula. The implementation of this formula helps in getting the result in a short period.
- This formula is also used in the simplification of complex problems of mathematics. The accuracy of this proportional formula is also good as this formula is very simple to implement. The chance of mistakes in this formula is very less.
