Tenths

Thousandths

Explanation

After the decimal point, the place values of the digits are, in order:

$\frac{1}{10^1} = \frac{1}{10}$

$\frac{1}{10^2} = \frac{1}{100}$

$\frac{1}{10^3} = \frac{1}{1,000}$

$\frac{1}{10^4} = \frac{1}{10,000}$ ...

The "6" is in the fourth place after the decimal point, so its place value is one ten-thousandth.
