Top Ender Giggles - Fractions

Last night Daddy was taking Baby Boy out on a secret Christmas errand (he went to Maplins, so I am guessing I have another Instructables Christmas gift) whilst Top Ender went to bed.

Top Ender has had three late nights in a row and as such was not impressed that Baby Boy was going out with her Daddy, as she felt she needed him in the house in order to go to sleep.

"It will now take me ages to fall asleep, an hour and a half! And you wont be back for an hour and two quarters!" she yelled stomping up the stairs

Daddy looked at me as we both did the math in our heads

"But they are the same!" Daddy called back
"Hmph" grunted Top Ender
