Step-by-step explanation:
On an ordinary clock, there are 24 hours.
1) 6/24 = 0.25 (The percentage in which the day has passed)
2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50
3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50
