Write 3/5 as decimal

 

For decimals,

  we need 10 in the denominator

So,

  3/5 = 3/5 × 2/2

        = 6/10

        = 0.6

We  can do the same for  other numbers as well

 

Write 1/2 as decimal

 

   1/2 = 1/2 × 5/5

         = 5/10

         = 0.5

 

∴ 1/2 = 0.5

 

Write 9/4 as decimal

  9/4

 

We know that

  4 × 25 = 100

So,

  9/4 = 9/4 × 25/25

       = 225/100

       = 2.25
