          We use the word percent often in everyday affairs. Let us find out the meaning of these words and learn how they are used.
          Look at the ratios  62/100 , 75/100   , 100/100 .
          The denominator of each of the ratios is 100. Such a ratio is called a percentage. A percentage is written using the word percent or the symbol %.
          The ratio  is written as 62% or 62 percent.
          Similarly,  means 75 percent or 75%.
                              means 100 percent or 100%.
