Question

Kahleen worked for 4 hours and 45 minutes how should she write that on her time card

Answer 1

Answer: 4.75hours or 4 3/4 hours.

Explanation:

To solve this problem you must apply the proccedure shown below:

- You know that one hour has sixty minutes:

1 hour=60 minutes.

- Therefore, you must convert 45 minutes to hours, as following:

`(45min)((1h)/(60min))=(3)/(4)h=0.75h`

- Add this result to 4 hours:

`4h+0.75=4.75h`

- Therefore she can write this as following:

4.75hours or 4 3/4 hours.
