Final answer:
Sam practiced soccer for a total of 115/72 hours.
Step-by-step explanation:
To find the total number of hours Sam practiced soccer, we need to add up the hours he practiced on each day.
On Friday, he practiced for 1 1/3 hours, which can be written as 4/3 hours.
On Saturday, he practiced for 3/8 hours.
And on Sunday, he practiced for 7/9 hours.
To find the total, we need to add:
4/3 + 3/8 + 7/9
First, we need to find a common denominator. The least common multiple of 3, 8, and 9 is 72.
Now, let's convert the fractions to have a denominator of 72:
4/3 = 32/24
3/8 = 27/72
7/9 = 56/72
Now we can add:
32/24 + 27/72 + 56/72 = 115/72
So, Sam practiced soccer for a total of 115/72 hours.
