its approximately 5.23
% error = difference/original*100
i.e: %error = (153-145)/8 *100
= 5.222 (approx 5.23%)

Error =153-145 =8
To find the percentage of error =(8/153)x100
=5.22875817%

there's a general formula for error percentages:
error = (difference of two values) / higher value
= (higher value - lower value) / higher value
% error = error x 100%
for your problem:
error = (153 - 145) / 153
= 8 / 153
% error = (8/153) x 100%
= 5.23%

153-145 = 8 gram difference
8 div. by 153 =.052 so his percentage of error is approx. 5%.
