It might have been possible to answer the question if the "following" multiplication had followed. But since you did not bother to make sure that it did, I cannot provide a more useful answer.
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
When performing a logarithmic calculation involving significant figures, the number of significant figures in the result is determined by the number of decimal places in the original values being used in the calculation. The result should be rounded to match the original value with the fewest decimal places.
When dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures in the calculation. Round the final answer to match the least number of significant figures in the original numbers.
The correct answer is 2. The three zeros between the decimal point and the 1 are place holders but they are NOT significant digits. See, for example, the Wikipedia link.
it supposed to read 17.6g(3 sigfig) + 92.800g(5 sigfigs) +0.0087g(2 sigfigs) = 110.4 another example would be 10400 mi (3 sigfigs) / 3.28* 10^2hr (3 sigfigs) = 31.7 and (21.4 * 7.35)-63.44=157.29-63.44=93.85 but writen as 94

To determine the answer with the correct number of significant figures, first identify the significant figures in each of the numbers involved in the calculation. The final result should be reported based on the number with the least significant figures among the values used. For addition and subtraction, the answer should be reported to the least precise decimal place, while for multiplication and division, it should match the number of significant figures of the least precise number used in the calculation.

There should be 3.
78.24 since you had two decimal places in the multiplier you'll have two in the answer.
The number of digits that reflect the precision of a calculation is known as significant figures or significant digits. These include all the non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. The precision of a calculation is determined by the least precise measurement used in the calculation, which sets the limit for the number of significant figures in the final result. Ultimately, maintaining the correct significant figures ensures that the uncertainty in measurements is accurately represented in the results.
To determine the correct number of significant figures in the final answer for the calculation (67.31 - 8.6 + 212.198), you first perform the subtraction and addition operations. The result of the subtraction (67.31 - 8.6) is 58.71, which has four significant figures. Adding 212.198 to 58.71 yields 270.908, which also has four significant figures. Therefore, the final answer should be rounded to four significant figures: 270.9.
6 of them.
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
To determine the number of significant figures in the answer to the calculation 65.25 m x 37.4 m, we look at the significant figures of each number. The number 65.25 m has four significant figures, while 37.4 m has three significant figures. The result should be reported with the least number of significant figures, which is three in this case. Therefore, the answer will have three significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
