Question

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each

Answer 1

Answer:

12

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

$\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12$

She needs 12 more sessions.

Answer 2

She needs to complete at least 16 lessons every week to reach 12 hours per week.
She has completed 3 hours / 4 lessons.
she needs to complete 12 more lessons to meet her weekly goal.
