Total of 55 marbles.....if there are 11 red marbles, then there are (55 - 11) = 44 green marbles. So the ratio of red marbles to green marbles is :
11:44 which reduces to 1:4 or 1/4 or 1 to 4
The number of practice hours per week for Maranda's piano recital is 13 hours
Overall practice hours = 52 hours
Number of weeks of practice = 4 weeks
Since, the number of practice hours per week is the same ;
Number of hours practiced each week can be obtained by dividing the overall practice hours by the number of weeks of practice.
Number of practice hours per week = Overall practice hours ÷ Number of weeks of practice
Number of practice hours = (52 ÷ 4) = 13 hours
Therefore, Marana practiced for 13 hours each week.
