Question

If you worked from 7:15 am to 12:45 pm, took lunch and then worked 1:45 pm to6:00 pm. How many hours (In Decimals) did you work that day?"

Answer 1

we have the following:

The first time in hours, normally, like this

`\begin{gathered} 7\colon15AM\rightarrow12\colon45PM=5\colon30h \\ 1\colon45PM\rightarrow6\colon00PM=4\colon15h \end{gathered}`

now, we calculate the total time:

`5\colon30h+4\colon15h=9\colon45h`

now we convert it to decimal form, knowing that 45 minutes is 3/4 of an hour, that is 0.75, therefore, the answer is:

`9.75h`
