Then, convert the ratio to a percent. And we can use Percentage Error to estimate the possible error when measuring. We can do this multiplying both the numerator and the denominator by 2 We get (15 × 2)/(50 × 2) = 30/100 = 30% Notice that in the problem above, if We can expresss the percent error with the following formula shown below: The amount of error is a subtraction between the measured value and the accepted value Keep in mind that http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/
