How many significant digits are in this 39.0?
Three. All non-zero digits are significant, all zeroes between other digits, and all digits to the right of the decimal. The reason for this is that if this is rounded off, it apparently is rounded off to the nearest tenth, otherwise the tenth place would not be shown. if it were rounded off to the unit, it would read 39, not 39.0 ■
