Rashid [163]
D. 0.0001.......first the zero before the decimal point is devided by 2....so it gives out 0 as a reminder so u right 0. at first then to do the part after decimal...first multiply 0.625 by 2 which gives out 0.125 as a fractional number so 0 would be the number after "0." ...and again the answer 0.125 is multiplied by 2 which gives out 0.25....so again we get a zero as an integer so now it would be "0.00..." ....again multiply 0.25 by 2 which gives out 0.5....again the integer is 0....so we add another 0 after 0.00....which would then become 0.000.....after that again multiply 0.5 by 2 which would give 1 as a result....as the fractional part is over, u need to stop here....so add that 1 after the 0.000 which gives 0.0001 as a final result.
