WebSep 29, 2024 · 100 only has 1 significant figure because the zeros after the 1 in 100 do not count since there is no decimal point after the last zero. Therefore, there is only 1 significant figure. 101 has 3 significant figures because all no zero numbers and any zeros between non zero numbers count. WebBy sig rules, any trailing zero before the decimal point does not count. For example, 1000, 100, 10 all have only 1 sig fig. E:g – 101 have 3 and 1001 have 4 significant figs respectively. How many sig figs is 60? 60 have an unlimited number of sig figs as rule depicted that all exact numbers have an unlimited number of significant figures. WebA Factor Pair of number 100 is a combination of two factors which can be multiplied together to equal 100. List of all possible Factor Pairs of 100: 1 x 100 = 100. 2 x 50 = 100. 4 x 25 = 100. 5 x 20 = 100. 10 x 10 = 100. 20 x 5 = 100. 25 x 4 = 100. barasch mcgarry salzman penson
