Approximate Value − Exact Value × 100% Exact Value Example: They forecast 20 mm of rain, but we really got 25 mm. 20 − 25 25 × 100% = −5 25 Example: You measure the plant to be 80 cm high (to the nearest cm) This means you could be up to 0.5 cm wrong (the plant could be between 79.5 and Steps 1 Know the formula for calculating percentage error. We can do this multiplying both the numerator and the denominator by 20 We get (1 × 20)/(5 × 20) = 20/100 = 20% I hope what I explained above was http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/
