Ber [7]

Answer:

3/8

Step-by-step explanation:

First,

convert 3/4 of an hour to minutes;

If 1 hr = 60 mins

then 3/4 of 1hr = $\frac{3}{4} *60\\ \\ =45 mins.Next, If 1/2 of 3/4 was spent practicing recital piece, it means that it is half of 45 mins;1/2 *45 = 22.5 minsLastly, convert the 22.5 mins into a fraction of an hour;22.5/60 = [tex]\frac{3}{8}$
