Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas.
Percent error = [(actual measured value)/(expected value) - 1] x 100%
Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide.
When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution.
Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error
Percentage error = 100*error/standard = 100*(3.98-3.14)/3.14 = 100*0.84/3.14 = 84/3.14 = 26.75%

How do you find percent markdown
There is no error. That's why it's impossible to find one.
how do you find a number when a percent of it is known
If it's high that means it's very off and away from the actual value. If you find a low percent error it is very close or close to the true value.

42 % of 41000 is the same as (42/100) x 4100. By performing the calculation you find that the answer is 17220.
nothing wrong
8*10-4
I would multiply 60 by 0.33
Well it depends on what you are trying to describe it as a percent of. If you are trying to find out what percent of 619 is of 100, the answer is 619%. If you are trying to figure out what 619 percent of 1000 is the answer would be 61.9 percent. If you are trying to find out what percent it is of a certain number you would do 6.19 multiplied by the number.
ERROR is the experimental value-accepted value.
It's obviously a fifth, so 20%. If it weren't obvious 17 x 100/85 is the calculation...
You have to do the following calculation: Old-new=change 13.99-12.99=1 change/old*100=±7
=(A1/B1)*100 then press Ctrl + Shift + % and the cell will be displayed as a percent
Percentage error = 100*error/standard = 100*(3.98-3.14)/3.14 = 100*0.84/3.14 = 84/3.14 = 26.75%
