QuestionRound the following calculations to the correct significant figures:
1. $\frac{23.72}{3.37}$
2. $9 + 2.8 - 0.135 + 10.6$
3. $\left(\frac{23.72}{3.37}\right) + 4.4$

Studdy Solution
Finally, we need to round the result of the division operation followed by the addition operation to the correct number of significant figures. The number with the least significant figures in the operation is4.4, which has two significant figures. Therefore, the result should also have two significant figures.
$$\left(\frac{23.72}{3.37}\right)+4.4=11.439 \approx11$$So, the rounded answers are7.04,20, and11.
