# College Physics Problem 1.18

## Solution:

### Part a

99 has 2 significant figures

100 has 3 significant figures

### Part b

$\displaystyle \frac{1}{99}\times 100\%=1.0\:\%$

$\displaystyle \frac{1}{100}\times 100\%=1.00\%$

### Part c

Based on the results of parts a and b, the percent uncertainties are more meaningful.
