Task: Calculating Boris's Free Time

To calculate the amount of time Boris can spend on games and relaxation, we need to determine the fractions of the day he spends on various activities. According to the given information:

- Boris spends 1/4 of the day at school. - He spends 1/8 of the day at home doing homework. - Boris spends 1/24 of the day at the dinner table. - He spends 3/8 of the day in bed.

To find the amount of time Boris has for games and relaxation, we need to subtract the time he spends on other activities from the total time in a day.

Calculation:

Let's calculate the total time Boris spends on other activities first:

- Time spent at school: 1/4 of the day - Time spent doing homework: 1/8 of the day - Time spent at the dinner table: 1/24 of the day - Time spent in bed: 3/8 of the day

To find the time Boris has for games and relaxation, we subtract the time spent on other activities from the total time in a day:

Total time in a day = 24 hours

Time spent on other activities = (1/4 + 1/8 + 1/24 + 3/8) * 24

Time for games and relaxation = 24 - (1/4 + 1/8 + 1/24 + 3/8) * 24

Now, let's calculate the result:

Time for games and relaxation = (1 - (1/4 + 1/8 + 1/24 + 3/8)) * 24

Time for games and relaxation = (1 - (6/24 + 3/24 + 1/24 + 9/24)) * 24

Time for games and relaxation = (1 - (19/24)) * 24

Time for games and relaxation = (5/24) * 24

Time for games and relaxation = 5 hours

Conclusion:

Boris can spend 5 hours for games and relaxation. This is equivalent to 5/24 of a day.
