take
x=0.25(bar on .25)
if two decimal places are there multiply by 100
but first into 10
x*10=0.25*10
10x=2.5
10x*10=2.5*10
100x=25
then subtract the old values
100x-10x=25-2.5
90x=22.5
x=22.5/90
x=0.25(bar on .25)

It should actually be let x=0.2525 100x=25.2525 subtracting x on both the sides we get 99x=25 so x will be 25/99
okk ..I had solved it

0.25(bar on 25)=25/99
I was actually taught in my school a simple method of solving such kind of questions where the whole part is 0 and all the digits in the decimal part have a bar on them
okkk .
If there is such a kind of a question den u just write the whole decimal part in the numerator and in the denominator put how many digits are in the decimal part so many 9's
thank you
For example if it is 0.4(bar on 4)=4/9
As only one digit is there so one nine
okkk
0.55(bar on 55)=55/99 two nines as two digits
okkk ..I understood. ..
Ohk
