4. When multiplying or dividing measurements written in significant figures, show the uncertainty of your calculations by rounding off your answer to . match the same number of significant figures as your least precise measurement (the measurement with the least number of significant figures). Example: 477.85 ( 32.6 = 14.657975 = 14.7

For example: 2.453 becomes 2.5 to two significant figures. 3. When the digit next beyond the one to be retained is exactly five, and the retained digit is even, leave it unchanged; conversely if the digit is odd, increase the retained figure by one (even/odd rounding). Thus, 3.450 becomes 3.4 but 3.550 becomes 3.6 to two significant figures.

12 has two significant figures and 3.00 has three, so the answer should only have two. For example, 3.20 x 5.04 = 16.128 ( 16.1. The starting values only have three significant figures each, so round the answer to three significant figures, 16.1.

If we are rounding to 2 decimal places, we leave 2 numbers to the right of the decimal. If we are rounding to 2 significant figures, we leave two numbers, whether they are decimals or not. Example 8. 243.7684 = 243.77 (2 decimal places) = 240 (2 significant figures) 1973.285 = 1973.29 (2 decimal places) = 2000 (2 significant figures)
