∙ 7y agoNon-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
Five - any zeros after the decimal are significant unless they're placeholders. Any zeros between significant digits are significant.
There are four significant figures in 15.50. All nonzero digits are significant, and the trailing zero is significant because it comes after a decimal point.
There are 5 significant digits in number 14500. To count for a given number as to how many significant digits does it have, look for the first zero form left and decimal point. For ex sample 0045 has 2 significant digits 0.0045 has 2 significant digits 0.4500 has 4 significant digits.
In this case, where there are no non-zero digits to the left of the decimal point, the number of significant figures is equal to the number of digits to the right of the decimal point from the rightmost figure to leftmost non-zero digit. In this case, there are four significant digits
270 has 3 significant digits.
How many significant digits does the following operation have?(40,200.0 * 0.000240) - 2.778
There are four significant figures in 47.10. The non-zero digits (4 and 7) are significant, as well as the zeroes following the decimal point.
No. 0.0000123 has three significant digits.

There are four significant figures in 15.50. All nonzero digits are significant, and the trailing zero is significant because it comes after a decimal point.
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.
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.
Four. Without a decimal, the trailing zero is not significant.
Four. The trailing zeroes are not significant because there is no decimal.
The two digits after the decimal point.
