Pizza Portions

My friends and I love pizza. Can you help us share these pizzas equally?

Red Balloons, Blue Balloons

Katie and Will have some balloons. Will's balloon burst at exactly the same size as Katie's at the beginning of a puff. How many puffs had Will done before his balloon burst?

In the Money

There are a number of coins on a table. One quarter of the coins show heads. If I turn over 2 coins, then one third show heads. How many coins are there altogether?

Pies

Stage: 2 Challenge Level:

Grandma had made pies for a bake sale. She had carefully put equal amounts of mixture in each pie tin and was now trying to find the weight of the pies.

She had a problem; she only had one $200$ gram weight and one $125$ gram weight.

She found that one pie balanced on the scale with both weights and a quarter of a pie.

How heavy was each pie?
