1) Look at the two numbers you are multiplying
2) Find both their number of significant digits
3) Multiply both numbers together normally
4) Round your answer to the same number of significant digits of the least number in the first two factors
250 x 185
250 had 2 sig. digits------ 185 has 3 sig. digits
250 has the least number of sig. digits (2)
Final answer has to have 2 sig. digits
Normal answer: 46250
With rounding of sig. digits: 46000

How many significant digits are in 4.00 and 7.0?
There are 3 significant digits in 4.00 and 2 significant digits in 7.0. Zeros between non-zero digits or at the end of a number after a decimal point are considered significant.
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)

3 significant digits because first zeros are just placeholders
How many significant digits does the following operation have (40200.0 0.000240) - 2.778?
To determine the number of significant digits in the result of the operation ( (40200.0 \times 0.000240) - 2.778 ), we first evaluate the multiplication. The term ( 40200.0 ) has 6 significant digits, and ( 0.000240 ) has 3 significant digits, so the product will have 3 significant digits (the least in the multiplication). When subtracting ( 2.778 ) (which has 4 significant digits), the final result should be reported to the least precise decimal place of the subtraction, which is determined by the number with the least decimal places (in this case, ( 2.778 ) has 3 decimal places). Therefore, the final result will have 3 significant digits.
How do you use significant digits in a sentence?
The number 202.45 has five significant digits.
Why do you use significant digits when dealing with measurements?
Measurements need to be specific so we use significant digits.
What is the number of significant figures in 10057?
There are 5 significant figures in 10057.-----------------When are Digits Significant? Non-zero digits are always significant. Thus, 22 has two significant digits, and 22.3 has three significant digits. With zeroes, the situation is more complicated: # Zeroes placed before other digits are not significant; 0.046 has two significant digits. # Zeroes placed between other digits are always significant; 4009 kg has four significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 ´103 has four significant digits 8.20 ´103 has three significant digits 8.2 ´103 has two significant digitsSignificant Digits in Multiplication, Division, Trig. functions, etc. In a calculation involving multiplication, division, trigonometric functions, etc., the number of significant digits in an answer should equal the least number of significant digits in any one of the numbers being multiplied, divided etc. Thus in evaluating sin(kx), where k = 0.097 m-1 (two significant digits) and x = 4.73 m (three significant digits), the answer should have two significant digits. Note that whole numbers have essentially an unlimited number of significant digits. As an example, if a hair dryer uses 1.2 kW of power, then 2 identical hairdryers use 2.4 kW: 1.2 kW {2 sig. dig.} ´2 {unlimited sig. dig.} = 2.4 kW {2 sig. dig.}
What is 123767474576 multiplied by 56745674?
You can calculate that on any calculator, and get a result with 10 significant digits or so - more than you need for most practical situations. In Excel, you get 15-16 significant digits. If you really want all the digits, you can:* Use the Wolfram Alpha website. Use "*" for multiplication. * Install a program that can handle more digits. For example, a Python interpreter will work just fine, and you can use it as a calculator.
4.832 has 4 significant digits as a result of which rule?
As a result of the rule that you use the definition of the term - such as significant digits - when finding them for a number.
Using proper signification figures what is the answer to the problem 55.0 m s 3.027 s?
It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.
When is a number significant or not significant?
Any non-zero digit is significant. Example: 352.12 has 5 significant digits. A zero is significant if it appears between non-zero digits. Example: 504.2 has 4 significant digits. A zero is also significant when it appears after the decimal point, AFTER other digits. In this case, it was only added to indicate a significant digit. Example: 5.30 has 3 significant digits. A zero after other numbers may or may not be significant. Use scientific notation to unambiguously indicate the number of significant digits. Example: 4500 has 2 significant digits. It may have 3 or 4 significant digits, but to be safe, assume 2 significant digits. A zero is NOT significant if it comes after the decimal point, BEFORE any other digits. In this case, it is only used to put the digits in their proper place. Example: 0.0024 has 2 significant digits.
What digits are considered significant in a measurement?
Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits. Zeros are sometimes significant and sometimes aren't: # Zeroes placed before other digits are not significant; 0.0968 has three significant digits. # Zeroes placed between other digits are always significant; 70063 kg has five significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 * 103 has four significant digits 8.20 * 103 has three significant digits 8.2 * 103 has two significant digits
How does the precision of a calculated answer compare to the precision of the measurements use to obtain it?
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
