If you have 5 apples and there are 20 apples altogether, then you have 5/20=0.25*100=25% of the apples. What Is A Good Percent Error Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) As Likewise, they often assume that the values that they derive through experimentation are very accurate.
