Question

Drew measured 50 cm of copper wire. The actual measurement was 45 cm. What is the percentage error?

Answer 1

Drew measured 50 cm of copper wire.

Actual measurement = 45cm

Error = Drew measurement - Actual measurement

Error = 50 -45

Error=5cm

For the error percentage:

`\begin{gathered} E\text{rror Perecentage}=\frac{Error}{Drew\text{ Measurement}}*100 \\ \text{Error Perecentage=}(5)/(50)*100 \\ \text{Error Percentage=10\%} \end{gathered}`

Answer: Error Percentage = 10%
