Luis is learning to play traditional Spanish guitar from his grandfather. The table shows the total number of hours he practiced over 3 days.

Days: 1, 2, 3
Practice Time: 1.5, 3.0, 4.5

In Day 1, Luis practiced for 1.5 hours.

In Day 2, Luis practiced for 3 hours.
In Day 3, Luis practiced for 4.5 hours.

Over the 1st 2 days, Luis practiced _____ hours per day

Over the 1st 2 days, Luis practiced (1.5 + 3.0)/2 = 2.25 hours per day.

Over the entire 3 day period, Luis practiced _____ hours per day

Over the entire 3-day period, Luis practiced (1.5 + 3.0 + 4.5)/3 = 3 hours per day.

To find the total number of hours Luis practiced over the three days, you need to add up the practice times for each day.

Day 1: Luis practiced for 1.5 hours
Day 2: Luis practiced for 3.0 hours
Day 3: Luis practiced for 4.5 hours

To find the total practice time, add up the hours from each day:

1.5 + 3.0 + 4.5 = 9.0

So, Luis practiced for a total of 9.0 hours over the three days.
