yes...please give me the idea to solve it.
+5
N=.xyzxyzxyz [email protected]

Multiply both sides by 1000

1000N=xyz.xyzxyz......   @2

Subtract 2 from 1..

999N = xyz

N= xyz/999

 

So to get the correct value of N we must multiply the rhs by a multiple of 999... Which is 4995 here...!

<p>Here it is a rational number ;to in Convert in P/Q form of the &nbsp;if you want to convert in P/Q form of any rational number then see on how many digits bar is there or how many digits are repeating here 3 digits are repeating so multiply it by 1000 so 1000N=xyz.xyzxyz.. subtract &nbsp;N=0.xyzxyzxyz we will get 999N= xyz there fore N=xyz/999 now only 4995 is divisible by 999 there D is the answer .</p>
