Answer:

$Orchestral\ Time = \frac{3}{10}\ hour$

Step-by-step explanation:

Given

$Time = 1\ hour$

$Musical\ Pieces = \frac{3}{4}\ hour$

$Practicing\ Sales = \frac{1}{4}\ hour$

Orchestral = $\frac{2}{5}$ of music practice time

Required

Determine time spent on orchestral pieces

From the given parameters, we have:

Orchestral = $\frac{2}{5}$ of music practice time

Substitute $\frac{3}{4}\ hour$ for music practice time.

So, we have:

$Orchestral\ Time = \frac{2}{5} * \frac{3}{4}\ hour$

$Orchestral\ Time = \frac{1}{5} * \frac{3}{2}\ hour$

$Orchestral\ Time = \frac{3}{10}\ hour$
