Here are the dimension of the oven tray jenny bakes the cake on. 600mm and 500mm. a cake tin is 25 cm in diameter. how many cake tins can jenny fit on the oven tray at one time?

First we have 2 types of units of measurement so let’s make all the same type.

600mm = 60 cm

500mm = 50 cm

Tray dimensions are 60 by 50 cm and is a rectangle

Cake tin is round and has diameter 25 cm

We can fit 2 rows and 2 columns of tins

Since (25+25) is less or equal to 50

And (25+25) is less or equal to 60

Answer 4 cake tins
