Question

The baking trays Riona uses are 640 mm x 420 mm. Each pizza has a diameter of 20 cm. How many pizzas can Riona fit on one baking tray?

Answer 1

we know that

Each pizza has a diameter of 20 cm-------> is equal to 200 mm

Divide 640 mm by 200 mm

640/200=3.2---------> 3 pizzas

Divide420 mm by 200 mm

420/200=2.1-------> 2 pizzas

therefore

The number of pizzas that can Riona fit on one baking tray is

3*2=6 pizzas

the answer is

6 pizzas
