What do you use significant figures for?
when rounding you want to choose an answer with the lowest significant figures to have a better answer choice
How many significant figures are needed when multiplying two numbers?
It depends on the number of significant figures from two numbers you are multiplying. But when multiplying you use the same number of significant figures from the numbers you are multiplying with the LEAST number of significant figures. Example: 92,873.239 * 2 = 200,000 (because the number 2 has only 1 significant figure even tho 92,873.239 has 8 significant figures your answer still only has 1 significant figure)
How many significant figures are in 3.040?
Four, if you assume that the final zero is not there simply to use up space!
How do you use significant digits to determine how to report a sum or product of two measurements?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How many significant figures are in 1.0200 X 10kg?
Assuming that the trailing 0s are not there simply to use up ink, the answer is 5.
How many significant figures will there be in the answer to 223.4times7.5?
In multiplication you use the lowest number of sig figs. if one number has 3 and the other has 5 the answer should be held to 3 digits. If one has a leading zero ( 0.123) the zero is ignored and the sig figs would be 3.Added:So the answer to the question "How many significant figures will there be in the answer to 223.4times7.5" is to be TWO in the answer of this multiplication (not 1675.5, not 1700, but 1.7*103)
List some rules used to determine the number of significant figures and how they differ for addition and subtraction vs multiplication and division?
For multiplication/division, use the least number of significant figures (ie 6.24 * 2.0 = 12). For addition subtraction, use the least specific number (ie 28.24 - 2.1 = 26.1)
What can you use to teach significant figures successfully?
There are many things you could use to teach significant figures successfully such as food. M n Ms. are an excellent food to use to teach significant figures.
What are the rules in multiplication and division of significant figures?
The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.
How many significant figures do you use for logarithms for example ln 3.02?
The number of significant figures after the decimal place matches the number of significant figures before the computation of the logarithm. Thus ln(3.02) would compute to 1.105. Three significant figures to four significant figures (3, after the decimal place).
How many significant figures should be reported in the answer -2.006?
Three, so the answer would be 3.96. Always use the number with the smallest amount of significant figures to determine the amount of significant figures will be in the solution.
How many significant figures are in 14 plus 3.078?
Take the least number of decimal places when adding or subtracting, therefore the answer is 17 to no decimal places.If it was 14 x 3.078 the answer would be 43 to 2 significant figures. The rule for multiplication/division is to use the least number of sig figs in the components: 14 has 2 and 3.078 has 4 so the answer should use 2.

How many significant figures are in 2804?
4 significant figures in 4400. A digit within a number is considered significant if: 1. it is a non-zero OR 2. It is a zero that is between two significant figures OR 3. It is a zero at the end of the number To express four thousand four hundred with two significant figures use scientific notation: 4.4 * 103

Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2
What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
