question
when adding numbers, the sum will have:
select the correct answer below:
as many decimal places as the number with fewest decimal places
as many decimal places as the number with more decimal places
as many significant figures as the number with fewest significant figures
as many significant figures as the number with more significant figures

Explanation:

When adding numbers, we follow the rule of significant figures for addition. The result should be rounded to the same number of decimal places as the number with the fewest decimal places among the addends. This is because the uncertainty in the least - precise number (the one with fewer decimal places) limits the precision of the sum. For example, if we add \(1.23\) (two decimal places) and \(4.5\) (one decimal place), the sum is \(1.23 + 4.5=5.73\), but we round it to \(5.7\) (one decimal place).

Answer:

as many decimal places as the number with fewest decimal places
