How do you fond the significant figure?

Answer 1

To figure out how many significant figures there are in a number you must first know the rules. All numbers 1-9 are counted towards the number of significant figures. The only number you need to worry about is 0.

-If there are 0's between digits (like 105), they are counted towards sig figs.

-If, to the right of a decimal point, the number ends in a 0, or multiple 0's (4.660), they all count towards sig figs.

-If, to the left of a decimal point, the number ends in 0 (4500), the 0 (or this case zeros) do not count towards sig figs.

-If there is a lone 0 to the left of a decimal point (0.112), the 0 does not count towards sig figs.

An example would be the number 0.4090

Automatically you know that the 4 and the 9 both count towards sig figs. Then you need to focus on the zero's. There is 1 lone 0 to the left of the decimal point, meaning that it does notcount towards sig figs. The 0 in between the 4 and the 9 counts towards sig figs because it is between 2 digits 1-9. The 0 on the end also counts because it is to the right of the decimal point. In all, this number has 4 significant figures.

Answer 2

The rules for identifying significant figures when writing or interpreting numbers are as follows:

1. All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5).

2. Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.

3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2.

4. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
