That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.

106, because values of 5 and higher 5 are rounded upwards and values of less than 5 are rounded downwards. Obviously 5.5 is greater than 5 so it is rounded up to 6.

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.

= significant figures = and got For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.

The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.

142.617 has 6 significant figures and should not be confused with the number of decimal places to which the number is given which is 3dp. To 5 significant figures, the answer is 142.62 To 4 significant figures, the answer is 142.6 To 3 significant figures, the answer is 142 To 2 significant figures, the answer is 140 (the final zero is retained to indicate the position of the decimal point which , if shown, would be 140.0 To 1 significant figure, the answer is 100

106, because values of 5 and higher 5 are rounded upwards and values of less than 5 are rounded downwards. Obviously 5.5 is greater than 5 so it is rounded up to 6.

The number of significant figures should be equal to the significant figures in the least precise measurement.

Because, to two significant figures, the value of 2,974894956..... is rounded off to 3,0The question was posed with three significant figures so you could argue that the answer should be 2,97.

There are 4 significant figures to be reported.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

But according to the rules of significant figures, the least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 11.

There are 4 significant figures to be reported.

The number 5321 has 4 significant figures.

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.
