Final answer:
The question involves calculations with significant figures, where the final result should match the precision of the least precise term. For example, when adding or subtracting numbers with different precision, the answer should be rounded to match the least number of decimal places. Similarly, in multiplication, the answer should match the least number of significant figures.
Step-by-step explanation:
It appears to involve the application of significant figures and calculations. When performing calculations, it's important to consider the number of significant figures in each number to ensure the final answer is as precise as the least precise measurement.
Examples:
- For the addition 56.0 + 3.44, the answer should have two decimal places because 56.0 has one decimal place, which is the least precise. The answer is 59.44, which should be rounded to 59.4.
- In the subtraction 45.99 - 32.8, the answer should have one decimal place because 32.8 has one decimal place, which is less precise than 45.99. The correct answer is 13.19, rounded to 13.2.
- For the multiplication 56.7 x 66.99, the answer should have the same number of significant numbers that the least accurate number has. 56.7 has three significant figures, so the product, which is 3797.963, should be rounded to 3800 when expressed with three significant figures.
Thus, to compute and express each answer with the proper number of significant figures, rounding as necessary, one must find the limiting term with the least number of significant figures to determine the precision of the final result.
