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.

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 express the measurement 37.26 m × 2.7 m × 0.0015 m in correct units and significant figures, first calculate the product: (37.26 \times 2.7 \times 0.0015 = 0.150165 m^3). The significant figures in the calculation are determined by the least precise measurement, which is 2.7 m (with 2 significant figures). Therefore, the final result should be rounded to 0.15 m³.
which is the correct product of the significant figures 3.278 and 4.23.

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.

78.24 since you had two decimal places in the multiplier you'll have two in the 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 you multiply 16 x 8.02 it equals 128.32, which has 5 significant figures. When you divide 28.58 into 128.32 it gives you 0.223 mL and it needs to be rounded to four significant figures.
In this sense, "reported to work" is correct. It's just an awkward sentence. You could change he first option to "reporting for work" and that would also be correct, but the position of the preposition is incorrect.
Rounding after each step in a calculation helps prevent errors from accumulating. It ensures that the final result is based on the correct number of significant figures and maintains accuracy throughout the process. This practice helps improve the precision of the calculated result.
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.
First it is an "invoice" not a "voice". Then the correct sentence is:- Dan reported that the contractor had sent in his invoice.
