Question

Amelia worked for 5 hours and 30 minutes. How should she write that on her time card?

Answer 1

She can write `5 1/2` hours or `5.5` hours.

Explanation:

The problem with writing time is that there are two systems.
The decimal system is based on powers of 10, while the time system is based on 60.

Amelia cannot write `5.3` this would mean `5 3/10` hours.

`30` minutes is `30/60 = 1/2 = 0.5` of an hour.

She needs to show 5 full hours and `1/2` hour.

`5 30/60` hours

She can write `5 1/2` hours or `5.5` hours.
