The number of significant digits in an integer ending in zeros is always ambiguous. It is not clear whether the number is accurate to the nearest hundred thousands (1 significant digit), ir to the nearest unit (6 sig digs).

There is 1 significant figure in this measurement.
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
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.
Seven (7) significant figures. All digits left of the decimal to the right of any leading zeros. All digits to the right. The zero is counted because it is significant that the measurement was taken to that level of precision. The full measurement may have been 1039.5201, .5202, etc. For whatever reason, the measurement was taken to 3 digits to the right of the decimal.
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
significant figures make data analysis less ambiguous and therefore much easier.. toindicatethe number of digits in a measurement
If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
