Question

If Allison practices her violin 12 hours a week and practices three fourths of an hour each day and has already practiced 3 hours how many mor lessons does she have to got to to complete the 12 hours

Answer 1

Answer = 12 lessons

Each lesson = 45 mins

That means 3hrs of practice is 4 lessons. 3 is a fourth of 12, so that means that 4 lessons is a fourth of all her lessons that she needs for 12 hours of practice. That means that she needs 16 lessons in order to have 12 hours of practice.

16-4=12

8hrs left to practice = 12 lessons left
