Hello, I'm in grade 8 looking for help on pie graphs. I know how to do them and place the angles with a protractor but I was wondering about a few things.

The assignment I was given was to put what you did in 24 hours.

My three things wereschool, sleeping, watching tv/eating.What I did was divided those numbers by 24 and got answers like: 0.29166666666 (7h/24) 0.375 (9h/24) 0.33333333333 (8h/24)

School: 7hours

Sleeping: 9hours

Watchingtv/eating: 8hours

Then I had to multiply those numbers by 360 because of the pie graph.

My questions are when should the decimal stop in those numbers because I wouldn't put 0.2916666666666 x 360

Please help, hope this is the right section.
