The last decimal digit of an answer is often rounded. Use the next digit to the right that is not to be placed into the division result. If this digit is greater than 4 (5 or larger) then round up by making the last right decimal digit one numeric value larger. Rounding our result of 4.142 would give us 4.143 (6 is greater than 4). It is 3 significant digits to the right of the decimal point.
