The number 10.989 rounded to 3 significant figures is 11.0
2.002
17.9867 to 3 significant figures is 18.0
The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.
0.036 The significant figures are indicated by the square brackets 0.0[35550], so we round this part of the figure.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Yes, it can be done.
The number 10.989 rounded to 3 significant figures is 11.0
72 is 72.2 rounded to two significant figures.
93.70

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).
Count the significant figures in each number. Calculate the minimum of these numbers. Do the multiplication Round the product to the LEAST number of significant figures, determined above.
e A number that has only 1 significant figure can't be rounded to 3 significant figures
86.346 +54.43 9.5 _______ 150.276 Now after we round the number and write it in significant figures , so it should look like this; 150 why? because when we need to round a number using the significant figures , we must look for the smallest significant figures which is 9.5 .

To convert the number 0.004758 to three significant figures, we need to round it off appropriately. Identify the significant figures: The given number, 0.004758, has 5 significant figures. Determine the significant figures based on the three most significant digits: The three most significant digits in 0.004758 are 4, 7, and 5. Round the number: Look at the digit immediately after the third significant figure, which is 7. Since 7 is 5 or greater, we round up the third significant figure (5). Apply rounding: The number rounded to three significant figures is 0.00476. Therefore, 0.004758 rounded to three significant figures is **0.00476**.
