Here we will show you how to calculate exactly how many hours, minutes, and seconds there are in 21/64 of a day. We will also illustrate what 21/64 of a day looks like on a pie chart.
Step 1) Calculate hours
We start by calculating the total number of whole hours in 21/64 of a day. There are 24 hours in a day. Therefore, we multiply 21/64 by 24. The whole number of the product we get is the number of hours.
21/64 × 24 = 504/64
504/64 = 7 7/8
= 7 hours
Step 2) Calculate minutes
Next we calculate the minutes. There are 60 minutes per hour. Therefore, we multiply the leftover fraction part from Step 1 by 60. The whole number of the product we get is the number of minutes.
7/8 × 60 = 420/8
420/8 = 52 1/2
= 52 minutes
Step 3) Calculate seconds
Finally, we calculate the seconds. There are 60 seconds per minute. Therefore, we multiply the leftover fraction part from Step 2 by 60. The product we get is the number of seconds.
1/2 × 60 = 60/2
60/2 = 30
= 30 seconds
Now we have the hours, minutes and seconds of 21/64 of day. When we put it all together we get our answer as follows:
21/64 of a day = 7 hours & 52 minutes & 30 seconds
Below is a pie chart showing 21/64 of day. To create the image, we first colored the whole pie in blue, and then we covered 21/64 of it in red.

Note that each pie slice above is one hour, and the whole pie is one day. Therefore, there are twenty-four slices.
