41 is a prime, hence the only way 41/24 can be reduced is to change to decimal numbers; to do so, click on 'Options' and select 'real numbers' in order to obtain a decimal answer.  The mixed fraction can be generated through Algebrator (a feature which has not been merged into doyourmath.com). 

I would recommend that you install the desktop Algebrator, provided to your annual subscription for no cost:
