Here we will show you how to calculate exactly how many hours, minutes, and seconds there are in 73/81 of a day. We will also illustrate what 73/81 of a day looks like on a pie chart.
Step 1) Calculate hours
We start by calculating the total number of whole hours in 73/81 of a day. There are 24 hours in a day. Therefore, we multiply 73/81 by 24. The whole number of the product we get is the number of hours.
73/81 × 24 = 1752/81
1752/81 = 21 17/27
= 21 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.
17/27 × 60 = 1020/27
1020/27 = 37 7/9
= 37 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.
7/9 × 60 = 420/9
420/9 ≈ 46.67
≈ 46.67 seconds
Now we have the hours, minutes and seconds of 73/81 of day. When we put it all together we get our answer as follows:
73/81 of a day ≈ 21 hours & 37 minutes & 46.67 seconds
Below is a pie chart showing 73/81 of day. To create the image, we first colored the whole pie in blue, and then we covered 73/81 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.
