Answer: 36 periods in a day

Explanation:

To find the number of periods in a day when each period is reduced to 40 minutes, you can use the ratio of the original period duration to the new period duration.

Original period duration = 45 minutes

New period duration = 40 minutes

The ratio of the original period duration to the new period duration is:

45 minutes / 40 minutes

Now, simplify this ratio:

(45/5) minutes / (40/5) minutes = 9 minutes / 8 minutes

So, each new period is 9/8 times as long as the original period.

Now, to find the number of periods in a day with the new 40-minute duration, you need to divide the total available time in a day by the new period duration:

Total available time in a day = 24 hours * 60 minutes = 1440 minutes

Number of periods with 40-minute duration = Total available time / New period duration

Number of periods = 1440 minutes / 40 minutes = 36 periods

So, when each period is reduced to 40 minutes, there will be a total of 36 periods in a day.
