When subtracting 100.5 from 200, what is the correct answer considering significant figures?
Step 1: Identify the numbers involved in the subtraction. We have 200 and 100.5.
Step 2: Perform the subtraction: 200 - 100.5.
Step 3: Calculate the result of the subtraction: 200 - 100.5 = 99.5.
Step 4: Check the number of decimal places in each number. 200 has 0 decimal places, and 100.5 has 1 decimal place.
Step 5: In subtraction, the result should be rounded to the least number of decimal places from the numbers involved. The least number of decimal places is 1 (from 100.5).
Step 6: Since our result is 99.5, it already has 1 decimal place, so we do not need to round it further.
