The answer is 0.031. While this can be solves really simply with a calculator it can also be easily solved by just looking at is you know the rules. The first digit after the decimal is the tenth place, the second is the hundredth, and the third is the thousandths. We can see that 31 is being divided by 1000 so we can infer that it will divide to the thousandths place. One can also count the number of zeros and move the decimal 3 places to the left. Ultimately there are many simple ways fins the answer, what matters most is what you will remember.
