Question

add the following measurements and type the sum into the text box. make sure your sum has the correct number of significant figures.
32.567 ml + 135.0 ml + 1.4567 ml =
(do not include units in your answer)

Explanation:

Step1: Add the numbers

First, we add the three measurements: \(32.567 + 135.0 + 1.4567\).
\[32.567 + 135.0 = 167.567\]
\[167.567 + 1.4567 = 169.0237\]

Step2: Determine significant figures for addition

In addition, the result should have the same number of decimal places as the number with the least number of decimal places. Among \(32.567\) (3 decimal places), \(135.0\) (1 decimal place), and \(1.4567\) (4 decimal places), \(135.0\) has the least number of decimal places (1). So we round \(169.0237\) to one decimal place.
Rounding \(169.0237\) to one decimal place gives \(169.0\).

Answer:

169.0
