There are two rules for determining the number of significant figures: ) If there is no decimal point-start at the RIGHT and count, beginning with the first non-zero digit. Examples 340 30400 34955 2 sf. 3 sf. 5 sf 2) If there is a decimal point--start at the LEFT and count, beginning with the first non-zero digit. Examples 340 3 sf. 5 s.f. 5 s.f 2 sf. 30400. 0.34955 0.00040 Determine the number of significant figures (s.f.) in each of...
