To convert a fraction to a decimal, you divide the numerator by the denominator. For a mixed number, you add the whole number to the fraction before converting to a decimal. Once you have the decimal, round to the nearest thousandth by looking at the fourth decimal place. For example, if you have 3/4, it is 0.75 as a decimal, which rounds to 0.750 to the nearest thousandth.
