what is the percent uncertainity implied by the numbers 1.1 and 9.9?
can someone show me how to do these kind of problms

If X = 1.1 it means X should be between 1.05 and 1.14999999999999999...
Basically, the uncertainty is ± 0.05
- if X is 1.05 it would be rounded to 1.1
- if X is 1.149 it would be rounded to 1.1
- if X is 1.04 it would be rounded to 1.0
- if X is 1.15 it would be rounded to 1.2
The %uncertainty for 1.1 is 100 x 0.05/1.1 = 4.5%
The %uncertainty for 9.9 is 100 x 0.05/9.9 = 0.51%

You are not clear. But if this is a lab class, then the percent diff between observed and actual = |observed - actual| x 100 / actual

not too sure what you are asking, but.: how about :
percent of uncertainity is: A. .9
and B. .1
hows that? good?
