Because there is no 'and' separating these numbers, we can assume that this will be all to the right of the decimal point. The decimal places are (from left to right) tenths, hundredths, thousandths, ten thousandths, and so on. The number we have here is thousandths, so it will go out three places. We know what seven hundred and eighty-six looks like, so all we have to do is place that entire number to the right of the decimal point.
seven hundred eighty-six thousandths = 0.786
Hope this helps!! :)
