After finishing his shift , a security guard wrote 6.75 "hours worked" on his time card . how long did he work?

6 hours 45 minutes.

Step-by-step explanation:

After finishing his shift, a security guard wrote  "6.75 hours worked" on his time card.

We have to calculate the time the guard has worked.

Now we convert (0.75) hours to minutes

0.75 hours = 0.75 × 60 minutes

                  = 45 minutes.

So total worked by security guard = 6 hours 45 minutes.

He worked 6 hours 45 minutes.

okay wait before i answer, is this for your points on a graph?
