Suppose we have fraction

  1/2

We want to convert it into percentage

 

How do we do it?

We know that 1/100 = 1%

 

So, we multiply & divide the fraction by 100

 

Thus,

  1/2  = 1/2 × 100/100

 = 100/2 × 1/100

 = 100/2 × %

 = 50%

 

We can also write directly

  1/2  = 1/2 × 100 %

 = 100/2 %

 = 50%

 

Convert 9/8 into percent.

    9/8 = 9/8 × 100%

  = 9 × 100/8 %

  = 9 × 50/4 %

  = 9 × 25/2 %

  = 225/2 %

         = 112.5%

Convert 2/3 into percent.

 

     2/3 = 2/3 × 100%

  = 200/3 %

  = 66 2/3 %
