The main attraction of this present study is that it has been dealt with the mathematical term “third proportional”. The third proportional value is the second term of the mean terms. An example can be drawn in this manner such as a:b = c:d, then ‘c’ will be the third proportional to ‘a’ and ‘b’. The attraction of this presentation is that it has been dealt with the formula of third proportionality. It is also going to define the process of finding the third proportion. This is the main attraction of this study and all the aspects make the study justified.       

Main body

The formula of the third proportion

• This can be written like a:b = c:d and in this field, the quantity ‘c’ is known as the third proportional to the quantities a, b, and d. For example, some quantities can be taken such as 7, 8, 9, and 10. Here the proportional form can be like 7:8:: 9:10 and ‘9’ is considered to be the third proportional to 7, 8, and 10.
• In proportion, different ratios have been used for the calculation of unknown qualities. It can be said that a proportion is the equity of different ratios. Third proportionality can be defined like this way and the above-mentioned formula is the main formula of it. This is the main factor of the present study and deals with it. 
• The formula also defines that there is a formula behind every proportional just like the third proportional and the formula has made the calculation successful. In this sense, if ‘a’ and ‘b’ have a continued proportion then ‘c’ is called the third proportional. In this field, it can be said that the third proportional proportion is the second term of the mean terms. This is the main aspect of this study and the description of this formula makes the study justified.         

Process of finding third proportion

• The process of finding the third proportion is the formula of the proportional. It can be considered as the main formula of the proportional and also the process of finding the third proportion. The important aspect of this study can be described through the formula and its execution in this field. The concept of third proportional is important and it describes the calculation process and the success of the process. 
• The process of finding is very simple and the formula is the same as mentioned before: a:b = c:d, then ‘c’ is the third proportional. It is the main process of finding the third proportional in this study. 
• Finding the process of the third proportion is nothing but the formula of it and it is valuable to the proportional calculation. Different terms can be taken in this study and their calculation can be made based on this formula. This is considered to be the process of finding the third proportion. 
• The calculation is the most important part of mathematics and it entirely depends upon calculation. Calculation of proportion or third proportional needs a basic formula for the discussion of it and the formula is the main base of the calculation. Therefore it can be said that the process is nothing but the formula of the third proportional.     

Different kinds of proportion

• There are different kinds of proportions in the mathematical field and they can be such as the “Fourth Proportional”, the “Third Proportional”, and the “Mean proportional”. These can be described differently with proper mathematical calculation. The third proportion is the main attraction of the present topic and has been described with elaboration in this field.
• The fourth proportional is the proportion of two ratios just like w:x:: y:z. This proportion can be written like this w:x = y:z and in this portion ‘z’ is known as fourth proportional to the quantities w, x, and y. This is the main formula and description of the fourth proportional in this study.
• Another important proportionality of this study can be mentioned and it is the “mean proportional”. The mean proportionality is mainly described with the use of square root. In this field, four quantities can be taken just like the above-mentioned proportions. The proportion of a, b, c, d can be described with the use of square root.
• The idea can be drawn that different types of proportionality are pregnant in the calculation of mathematics and they are considered to be important aspects of this field.             

Conclusion

The main attraction of this present study is the proportion and the third proportion has been described here with much elaboration for the satisfaction of the study. It is considered to be an important aspect of the mathematical field. The field of mathematics has become enriched with the presence of the proportion and mainly the third proportional. The formula of the present proportional is a:b = c:d, then ‘c’ becomes the third proportional of this calculation or formula. The description of the third proportion in this study has been mentioned with examples for the easy-going of this study. The application of the FAQs has made the study justified in this field. It is considered to be the most important aspect of this study.
