Question 838999: Julie spends 720 minutes per week practicing the piano outside of class. Her ratio of time spent on practicing pieces to time spent on scales and theory is 5 to 3. How many HOURS per week does she spend on practicing pieces? How many HOURS per week does she spend on scales and theory?
I have used the problem of 5/3=x/y but it gives me another equation. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! First, convert minutes to hours
( minutes ) x ( hours/minute ) = hours hrs
------------------------------
Let = her time in hours spent on pieces per week = her time in hours spent on scales per week
----------------------------------------------------
Multiply both sides by
She spends 7 1/2 hours per week on pieces
She spends 4 1/2 hours per week on scales
---------------------

OK
