Best Answer

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 18 plus 52.1?

There are three significant figures in the sum of 18 plus 52.1 because each number has three significant figures and adding them together maintains the precision of the original numbers.


What is the answer of 23.1 plus 2.06 in significant figures?

It depends how many significant figures you are after. 23.1 + 2.06 = 25.16Significant figures is like rounding.If I were to round it to 3 sig. fig. I would have 25.2If I were to round it to 2 sig. fig. I would have 25and so on. You only keep the numbers which keep the number similar to the original yet less accurate with less digits.


The significant figures in a measurement include?

The significant figures in a measurement include all known digits plus one estimated digit. All non-zero digits are considered significant, zeros between non-zero digits are significant, and zeros at the end of a number and after a decimal point are significant.


What concludes the number of significant figures that should be maintain in recording the measurement?

The number of significant figures in a measurement is determined by the precision of the measuring instrument. Include all certain digits plus one uncertain digit (estimated or interpolated). Nonzero digits, zeros between nonzero digits, and trailing zeros in numbers containing a decimal point are considered significant.
