to determine sig figs you eed to know how many sig figs are in the calclation.
in adding and subtracting you answers are to the sig fig with the lowest dec point place.
and in multiplication and dividing sig figs of answers determined by the number with the least sig figs in the calculation
ex.
5.2 ( 2 sf) + 5.324 (4 sf) = 10.5 ( because 5.2 has the largest decimal place)
5.2 X 5.324 = 28 ( because 5.3 only has 2 sf so the answer ca only have 2sf)

When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
How many significant figures does the result of the following operation 8.52010 and times 7.9?
The product is 67.30879 which means it has 7 significant figures
In adding the measurements 11.074m 18.2m and 16.943m what should be the number of significant figures in the result?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is 20.56120 g rounded to three significant figures?
20.6 is the result.
How is precision related to the significant figures in a measured quantity?
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
How many significant figures would be in theresult of the multiplication of 2.305956 and 198.40?
The result is 457,50 - with two significant figures.
What is the significant figures 4.884 x 2.25?
4.884 has four significant figures and 2.25 has three significant figures. 4.884 x 2.25 = 10.989 = 11.0 rounded to three significant figures. When multiplying or dividing, the result must have the same number of significant figures as the number in the problem with the fewest significant figures.
How does conversion factors affect the number of significant figures in a problem?
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
When 64.4 is divided by 2.00 what is the correct number of significant figures in the result?
32.2
When blank two numbers the result should have the same number of significant figures as the factor with the smaller number of significant figures?
multiplying
How many significant figures does the result of the following operation 8.52010 and times 7.9?
The product is 67.30879 which means it has 7 significant figures
What Is 9682 rounded to tree significant figures?
The result is 9,680
In adding the measurements 11.074m 18.2m and 16.943m what should be the number of significant figures in the result?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
A student calculates the density of an unknown solid The mass is 10.04 grams and the volume is 8.21 cubic centimeters How many significant figures should appear in the final answer?
The general rule is that the final result should not be more accurate than the numbers used to obtain this final result. In the case of a multiplication or division, this means that the final result can't have more significant digits than the original numbers. One of the numbers has 4 significant figures, the other 3; therefore, the final result should be rounded to 3 significant figures. If more significant figures are quoted, a special note should be made that the last digits are uncertain.The general rule is that the final result should not be more accurate than the numbers used to obtain this final result.

What are the rules in performing operations involving significant figures?
You make you're calculations using has many (or more) significant figures as requested without any further considerations until you get to the final result... You reduce the final results significant figures to the requested one or add zeros at the end to match it if it is an exact result
