1). 1/552). 18/1003). 18/10004). 1/66

Answer»

By looking at the options we can SAY that the options B & C can be RULED out as they result in a terminating NON - recurring decimal numbers i.e.,

18/100 = 0.18 & 18/1000 = 0.018

So let us check the other options:

$(\begin{array}{l} 1/55{\rm{\;}} = {\rm{\;}}0.0181818 \ldots .{\rm{\;}} = {\rm{\;}}0.0\overline {18} \\ \therefore {\rm{\;}}0.0\overline {18} \; = \;\frac{1}{{55}} \END{array})$
