Theory:

Ajay and Jeevitha went shopping together. Initially, Ajay had \(₹500\) and Jeevitha brought \(₹1500\) to buy some groceries. Suppose, if Ajay spent \(₹400\) from the total amount and Jeevitha purchased the goods worth \(₹800\) from the total amount, can you tell me who has spent more?
 
Since the initial amount they had are not the same, so we can decide who has spent more, just by comparing the amount they spent. So, we need another comparing quantity; "Percentage" to get an answer for this sort of situations.
Let us see some fundamental ideas of "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:
43 per cent is written as 43 \(\%\), and it means that "43 out of \(100\)."
Conversion of Percentage:
 
DecimalFractionPercentage
\(0.01\)\(1/100\)\(1\)\(\%\)
\(0.1\)\(1/10\)\(10\)\(\%\)
\(0.2\)\(1/5\)\(20\)\(\%\)
\(0.25\)\(1/4\)\(25\)\(\%\)
\(0.5\)\(1/2\)\(50\)\(\%\)
\(0.75\)\(3/4\)\(75\)\(\%\)
