You can put this solution on YOUR website!

If Sheila practiced 1+%281%2F2%29 hours Monday, 3+%283%2F4%29 hours Tuesday, and 2+%281%2F4%29 hours Wednesday, then all you need to do is add them:
you can do it this way:
1+%281%2F2%29hours+%2B+3+%283%2F4%29hours+%2B+2+%281%2F4%29hours+
1hour+%2B+3hours+%2B+2hours+%2B+%281%2F2+%2B+3%2F4+%2B+1%2F4%29hours+
6hours+%2B+%282%2F4%2B+3%2F4+%2B+1%2F4%29hours+
6hours+%2B+%286%2F4%29hours+
6hours+%2B+1%282%2F4%29hours+
6hours+%2B+1%281%2F2%29hours+
7%281%2F2%29hours+.......the total number of hours that she practiced

or, you can do it this way:

1+%281%2F2%29hours+%2B+3+%283%2F4%29hours+%2B+2+%281%2F4%29hours+

%283%2F2%29hours+%2B+%2815%2F4%29hours+%2B++%289%2F4%29hours+
%286%2F4%29hours+%2B+%2815%2F4%29hours+%2B++%289%2F4%29hours+
%2830%2F4%29hours
7%282%2F4%29hours
7%281%2F2%29hours
