5.2g When you add or subtract using significant figures, you round the answer to the fewest number of decimal places as the measurement with the fewest decimal places.
Multiplication and DivisionRound the answer to the same number of significant figures (sig figs) as the measurement with the fewest sig figs in the problem.34.9cm x 4.7cm = 164.03cm2 = 160cm2 (rounded to two sig figs)271.0g/99.8cm3 = 2.71543g/cm3 = 2.715 (rounded to four sig figs)Addition and SubtractionRound the answer to the fewest decimal places as the measurement with the fewest decimal places.9.45kg + 8.329kg = 17.78kg (rounded to two decimal places)

4.884 has four significant figures and 2.25 has three significant figures. 4.884 x 2.25 = 10.989 = 11.0 rounded to three significant figures. When multiplying or dividing, the result must have the same number of significant figures as the number in the problem with the fewest significant figures.
Two. When multiplying or dividing the answer is rounded to the fewest significant figures in the given measurements. 0.55 has only two significant figures, so the answer can have only two significant figures.

When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).
5.2g When you add or subtract using significant figures, you round the answer to the fewest number of decimal places as the measurement with the fewest decimal places.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
The product of 0.12 g, 1.8 g, and 0.562 g should have the same number of significant figures as the measurement with the fewest significant figures, which is 0.12 g in this case. Therefore, the product should be expressed with two significant figures.

The sum of 5.1 and 3.2 is 8.9 with two significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places, which in this case is 3.2.
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
