we know that
The diameter of a half dollar is equal to [tex] 1.205\ inches[/tex]
[tex] 1.205=1+2*(0.1)+5*(0.001)\\1.205=1+0.2+0.005[/tex]
so
The value of the [tex] 5 [/tex] in the diameter is equal to [tex] 0.005 [/tex]
and
[tex] 0.005 [/tex] is equal to say [tex] 5\ thousandths[/tex]
therefore
the answer is
[tex] 0.005 [/tex] or [tex] 5\ thousandths[/tex]
