Percent Error — Quiz

Question 2 • Grade 7 Mathematics

Jenny predicted that she would sell 12 bracelets, but she actually sold 16 bracelets. Which expression would find the percent error? Use the given table to help answer the question. Percent Error Item Approximate value Exact value Error Absolute error Ratio Percent error Bracelets 12 16 negative 4 4

Answer
A
negative 4 over 12 times 100
B
4 over 16
C
4 over 16 times 100
D
negative 4 over 12

Explanation

Percent error is the absolute error divided by the exact value, then multiplied by 100. The table gives an absolute error of 4 bracelets and an exact value of 16, so the expression is 4 ÷ 16 × 100. Choice C matches this calculation; using the predicted value of 12 would use the wrong denominator.
