Answer:
5.5%
Explanation:
The absolute error: 34.5-32.7=1.8
Percentage error: Relative error * 100%
To get the relative error, you can calculate it by (absolute error)/(actual value) or (max error)/(measured value)
Since you only have the absolute error and actual value, let's calculate it using that method.
(1.8/32.7)*100%=~5.5%
