ILLUSTRATIVE EXAMPLES
EXAMPLE1 Express the following decimals in the form
(I) 0.32(bar is on 2)
(ii) 0.123(bar is on 3
(I) 0.00352(bar is on 2)

​

Answer 1

(i) 0.32 = (32-3)/90 =29/90

How did I do ?

Lets see the denominator first..

Decimal ke bad jitne bhi no. bar ke niche hai unke liye 9 likho ...0.32 me sirf ek no. niche h to 9 likha....fir jitne number bina bar k niche hai utne hi 0 likho 9 k aage....yha sirf ek no. hi hai...to ek zero aagya....aisa krke denominator aagya 90.

Lets come to numerator portion now...

Decimal ke bad jitne bhi number hai wo as it is likho....0.32 me 32 hai to 32 likha.

Then ab decimal k bad jo bhi number bina bar ke hai unhe minus kr diya...32 me 3 bina bar ke hai...to isliye numerator aagya 32-3 =29

and denominator =90

So 29/90
