Answer:
6.667%
Step-by-step explanation:
Given that:
Actual measurement = 7.5 mm
Measured value = 7 mm
Percentage error :
Error / (Actual measurement.) * 100%
(Actual measurement - measured value)
Error = 7.5 - 7 = 0.5 mm
Percentage error = (0.5 / 7.5) * 100%
Percentage error = 0.0666666 * 100%
= 6.667%
