Objective:

In the previous chapter, we learned about percentages, and it's conversation method.
 
In this chapter, we will look at how we use the percentage as a measuring unit in our day to day life.
 
Before that, let's recall what we have studied in the previous chapter.
Percentage:
 
The term "per cent" means per hundred or for every hundred. This term has been derived from the Latin word "per centum".
 
We use the symbol (\(\%\)) for the term per cent.
Example:
20 per cent is written as 20 \(\%\), and it means that "20 out of \(100\)."
Conversion of Percentage:
