Answer:

17.5%

Step-by-step explanation:

Subtract one value from the other. (i does not matter the sign)  

 400 − 330 = 70, so his error is 70

Now  find the Percentage Error:

Divide by the exact value and make it a percentage:

70/400 = 0.175 = 17.5%
400 - 330 = 70 (difference)
p/100*400 = 70
p/100 = 70/400
p/100 = 0.175
p = 0.175*100 = 17.5% (percent of error)
