Answer for screen readers
The percentage of 4 hours and 30 minutes in one day is $18.75%$.
Steps to Solve
- Convert the time to hours
First, we need to convert 4 hours and 30 minutes into a single unit: hours.
30 minutes is equal to $0.5$ hours.
So, $4 \text{ hours} + 0.5 \text{ hours} = 4.5 \text{ hours}$.
- Set up the percentage calculation
To find out what percentage $4.5$ hours is of $24$ hours (a full day), we can use the formula:
$$ \text{Percentage} = \left( \frac{\text{part}}{\text{whole}} \right) \times 100 $$
In this case, the part is $4.5$ hours and the whole is $24$ hours.
- Perform the calculation
Now we can substitute the values into the percentage formula:
$$ \text{Percentage} = \left( \frac{4.5}{24} \right) \times 100 $$
- Calculate the result
Now, we calculate:
$$ \text{Percentage} \approx \left( 0.1875 \right) \times 100 = 18.75% $$
The percentage of 4 hours and 30 minutes in one day is $18.75%$.
More Information
This calculation shows that 4 hours and 30 minutes is approximately one-fifth of a day, which is a helpful way to understand how much time that represents in the context of a full day.
Tips
- Not converting minutes to hours correctly: Always ensure to convert all time units to the same measurement before doing calculations.
- Misunderstanding the percentage formula: The part must be divided by the whole, and the result multiplied by 100 to get the correct percentage.
