Derrick studied for 13 and 1/2 hours this week for a spelling bee.

we have to find percentage of the number of hours in a day

time taken by Derrick = 13 + 1/2 = 27/2 hours .

total taken in a day = 24 hours

so, percentage of the number of hours in a day = time taken by Derrick/total time in a day × 100

= (27/2)/24 × 100

= 2700/48

= 56.25 %
