ANSWER and EXPLANATION

We want to find the number of minutes she practiced each day and in total.

An hour is equal to 60 minutes.

On Monday, she practiced 1/2 of an hour. To convert this to minutes, multiply 1/2 by 60 minutes. That is:


\begin{gathered} (1)/(2)\cdot60 \\ \Rightarrow30\min \end{gathered}

On Tuesday, she practiced for 1/3 of an hour. That is:


\begin{gathered} (1)/(3)\cdot60 \\ \Rightarrow20\min \end{gathered}

On Wednesday, she practiced for 1/4 of an hour. That is:


\begin{gathered} (1)/(4)\cdot60 \\ \Rightarrow15\min \end{gathered}

On Thursday, she practiced for 1/4 of an hour. That is also equal to:


\Rightarrow15\min

On Friday, she practiced for 1/2 of an hour. That is equal to:


=>30\min

To find the total number of minutes that she practiced in all during the week, find the sum of the number of hours for all the days given.


\begin{gathered} 30+20+15+15+30 \\ \Rightarrow110\min \end{gathered}

She practiced for 110 minutes during the week.
