To find out how many practice sessions Sarah needs to reach her goal of 6,075 minutes, we can divide her total practice goal by the length of each practice session.
Sarah practices for 45 minutes each session.
We can calculate the number of sessions as follows:
\[ \text{Number of sessions} = \frac{\text{Total practice minutes}}{\text{Minutes per session}} = \frac{6075}{45} \]
Now, we can perform the division:
\[ \frac{6075}{45} = 135 \]
Thus, Sarah will need to practice for 135 sessions to reach her goal of 6,075 minutes.
