I recently joined a company as a trainee and we have to skype our priorities or task that we are going to do on that day.
For example, people write priorities like this:
1. HTML/CSS training - [0.5 hours].
2. PHP training - [9 hours].
Now I do know about quasi possessive but this doesn't sound like a quasi possessive. I want to know whether it should be 9 hour or 9 hours? Maybe it might be 9 hours because it's more than 1 but writing 0.5 hours seems a bit confusing. Please let me know what's the correct usage. Thank you.
