WebNumber of sig figs is the number of digits reported, not including any zeroes to the left of the first non-zero digit. For example, 3.00 has 3 sig figs, 0.0045 has 2 sig figs and 3.0400 has 5 sig figs. Ambiguity. With no decimal point, the number of significant figures in the number 100,000 is ambiguous.
WebSo if we are dividing 23 by 448, which have two and three significant figures each, we should limit the final reported answer to two significant figures (the lesser of two and three significant figures): 23 ÷ 448 = 0.051339286… = 0.051.
