Answer
$11\frac{203}{500}$
Work Step by Step
To convert a decimal to a fraction, place the decimal value in the numerator. Set the denominator to a multiple of ten, corresponding to the rightmost place value, in the case thousandths.
Simplify by dividing the numerator and denominator by the greatest common factor.
$\frac{406}{1000}=\frac{406\div2}{1000\div2}=\frac{203}{500}$
Write the whole number portion to the left of the fraction.
