A teacher had to mark 100,000 books she had a month to do it. She spread it out over that month (31 days) how many books could she mark a day and if there is any left over how many?
100,000 / 31 = 3225.806452
but .806452 * 31 = 25
so
3225 and 25 left to do on Christmas
Does she never take a day off?
She is quite a marker.
