four
13.00 has 4 sig figs.
if a zero is before the first nonzero number, exclude it. ex: .00023 is 2 sig figs. count any zeros after the number and between. ex: 2.00530 is 6 sig figs.
Sig figs are unaffected by being converted from decimal form to a percentage (or vice versus). The reason being is that you will multiply your decimal answer which has a limited number of sig figs by the exact number 100, and by being exact it technically has infinite sig figs.
There are 3 sig figs becasue when you multiply two numbers you take the same number of sig figs as the multiple with the fewest sig figs. 0.280 and 3.70 both have 3 sig figs.
There is one sig fig in the number 4000.

There is one sig fig in the number 4000.
There is one sig fig in the number 1.
There is 1 sig fig in the number 2.
there are 3 sig figs. 4, 0, and 5 are the sig figs
there are 4 in the solution because the numbers are multiplied in the end, the solutions will have the same number of sig. figs. as the number in the problem with the lowest number of sig. figs. Ex: the lowest number of sig figs is 4 because 0.0107 has 4 sig figs.
In addition and subtraction you take the most number of sig figs. 312.45 - 3.0 = 3.0945 X 10^2 5 sig figs 2 sig figs answer needs to have 5 sig figs In multiplication and division it is the least number. 312.45 X 3.0 = 9.4 X 10^2 5 sig figs 2 sig figs answer needs to have at MOST 2 sig figs in decimals if there is no number before the decimal, i.e.; 0.xxxx then leading zeros do NOT count as significant. Meaning 0.000010 is only 2 significant figures. The 1 and the zero after the 1.
