no he did not spend 110% more time doing homework if he did it would be 12hrs to find this put 11 in its decimal form and multiply it by 110 =12.1

The answer is incorrect because 11-10=1. and 1÷10 is 10. 10(100) Is 10%. Marcus just added a zero to eleven and turned it into a percent . This is why Marcus is incorrect
