Suppose I have decimal

  0.5

 

To continue into percentage

We just multiplying by 100%

0.5 = 0.5 × 100%

      = 5/10 × 100%

      = 5 × 10%

      = 50%

 

Note:-

The concept behind this is

     Percentage is 1/100

      That is 1/100 = %

 

So, to convert any number into percentage,

We multiply by 100/100

 

Like here

          0.5 = 0.5 × 100/100

10.jpg

 

  = 0.5 × 100 %

  = 5/10 × 100%

  = 5 × 10%

  = 50%

 

Let’s do some examples

 

Convert 1.125 into percent

1.125 = 1.125 × 100%

= 1125/1000 × 100%

= 1125/10 %

= 112.5%

 

Convert 0.66 into percent

0.66 = 0.66 × 100%

= 66/100 × 100%

= 66/1 %

= 66%
