What Fraction of a Day is 8 Hours and 20 Minutes?

It can be intriguing to figure out what portion of a day certain time durations represent. This article explores in detail how 8 hours and 20 minutes contribute to a full day in terms of fractions. We will also delve into some related concepts and provide clear, step-by-step calculations.

Converting Time to Decimal Form

To understand how much 8 hours and 20 minutes are in terms of a day, we can convert the time into a decimal form. Here's the step-by-step process:

First, we convert 8 hours into a fraction of a day. Since there are 24 hours in a day: 8 hours 8 / 24 1 / 3 of a day. Next, we convert 20 minutes into a fraction of an hour and then a fraction of a day: 20 minutes 20 / 60 1 / 3 of an hour. Adding these fractions together, we get: 1 / 3 1 / 3 2 / 3 This can be converted to a decimal for a clearer understanding: 2 / 3 0.6666666667, or simply 0.67 of a day.

It's also useful to convert 8 hours and 20 minutes into total minutes and then convert that to a fraction of a day. Here's how:

Convert 8 hours to minutes: 8 x 60 480 minutes. Add the remaining 20 minutes: 480 20 500 minutes. There are 1440 minutes in a day, so: 500 / 1440 0.3472222222, or 0.35 when rounded to the nearest hundredth. This fraction can also be simplified to 25 / 72.

Alternative Method: Fractional Representation

Another approach to finding the fraction is to directly use the total minutes divided by the total minutes in a day:

8 hours and 20 minutes is 500 minutes. 1440 minutes in a day. 500 / 1440 25 / 72, which is about 0.3472 of a day.
