Comments (10) on “Using the rules of significant figured, what do you get when you subtract 15.54 from 508.9538?”
To answer to the question above, when adding or subtracting measurements (numbers), the result must have the same number of decimal places as the number in the problem with the fewest decimal places.
24.545 + 307.3 = 331.845
However, the answer must be given to the correct number of decimal places, in this case, 1 in 307.3.
So the result of the addition of 24.545 and 307.3 should be 331.8.
According to the rules for significant figures, simple decimal subtraction is done. But since 15.54 is only accurate to the hundredths place, then the resulting difference should also be rounded off to the nearest hundredths. This is shown below:
Explanation: We have been asked to subtract 15.54 from 508.9538.
Thus 508.9538 - 15.54 = 493.4138
By using the rules for significant figures for subtraction, round the answer to the least number of places to the decimal point of any number in the problem. As one number contains 2 decimal places and the other number contains 4 decimal places.
Thus the answer should have 2 decimal places. Thus the answer should be 493.41.
You get 493.41 when you subtract 15.54 from 508.953 using the rules for significant figures.
For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers ONLY. Here is what to do:
1) Count the number of significant figures in the decimal portion of each number in the problem. (The digits to the left of the decimal place are not used to determine the number of decimal places in the final answer.)
2) Add or subtract in the normal fashion.
3) Round the answer to the LEAST number of places in the decimal portion of any number in the problem.
The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

-493.4138 that's what I got when you subtract 15.54 from 508.9538
When we subtract 15.54 from 508.9538 using the rules for significant figures, the answer would be 493.41.
The rule for adding and subtracting numbers is that the lowest decimal places should be followed for the answer to be in a significant figure.
I hope my answer has come to your help. Thank you for posting your question here in
When we subtract 15.54 from 508.9538 using the rules for significant figures, the answer would be 493.41.
Explanation:
According to the rules for significant figures, simple decimal subtraction is done. But since 15.54 is only accurate to the hundredths place, then the resulting difference should also be rounded off to the nearest hundredths. This is shown below:
508.9538 - 15.54 = 493.4138
Rounding off to the nearest hundredths:
= 493.41
When you add 24.545+307.3= 331.845
You will go with the number with the smallest number, which is 307.3.
So answer will be 331.8
