Answer

Find out the how many hours has Carlos practiced piano .

To prove

As given

He\ practices\ piano\ for\ \frac{3}{4}\ hour\ before\ school.

\frac{7}{10}\ hour\ when\ he\ gets\ home.

Total\ hours\ carlos\ practiced\ piano = \frac{15+14}{20}

Total\ hours\ carlos\ practiced\ piano = \frac{29}{20}\ hours
