The oven tray is 600mm by 500mm. A cake tin is 25cm in diameter. How many cake tins can jenny fit on the oven tray at one time?

600 / 25  = 24 500 / 25 = 20 Number of cakes to fill the tray = 20*24  = 480

600 divided by 25 = 20 500 divided by 25 = 24  so 20 x 24= 480 so 480 cake tins can fit on the oven tray at one time
