LUK EVRY 1 ITS QUITE SIMPLE:
first let us suppose the decimal as x i.e x=0.232323... eq 1
after dat as we can see the digits r repeating after 2 digits
i.e. 23 so we just have to multiply the decimal no. by 100 and
dat will make 100x=23.232323...eq2
now simply subtract eq2 by 1 u will get the required result

Why it is only multiply by 100? Please explain.

If only 2 digits are repeating then you hav to multiply by 100.
If 3 digits are repeating the multiply by 1000 and so on.

Write the repeated figures only once in the numerator and take as many nines in the denominator as is the number of repeating figures.

It is simple. All you need to do is just put as many as nines in denominator which are recurring or under the bar. In numerator remove the bar sign.

Please explain this question 23 is repeated 3 times but we have added 9 (2 times in denominator not 3 times) why.

There are dots (....) after 23 i.e. 23 is repeated infinitely .232323232323232323...
But only two 'digits' - 2&3 are repeating so taken 2 9's.
