Rules for Rounding: A. If the digit to be dropped is less than five, simple eliminate it. 134.3 g to 3 sig. Figs. = 134 g. B. If the digit to be dropped is more than five, (or a 5 followed by any non zero) add 1 to the preceding digit. 134.6 g to 3 sig. Figs. = 135 g 134.501 g to 3 sig. figs. = 135 g
