Well look at.the thousandth spot .143 okay there is no oneths spot behind the decimal only in front of it, so the third number would be the thousandth place. Now if we are to round we have to look one number behind the thousandths place. .1435, the place behind the thousandths is 5 or more so we are going to round the thousandths place up one. So your answer would be .144.
