Iam a decimal
if you double me,my double is between 0.6 and 0.7,
but closer to 0.6.
my thousandths digit is not a 2.
but the thousandths digit of my double is.
what decimal might i be?

Numbers greater than 0.3 and less then 0.35 are between .6 and .7 when doubled.

Lets assume it is a decimal that goes up to the thousandths. 
0.310 to 0.324 Would be closer to .6 than .7. We know the thousands digit has to be a 1 or a 6 because its double ends in a two. So it looks like our options are .311, .316 and .321.
