Question

The cost of a 300g jar of coffee is £1.20 How much coffee do you get for 1p?

Answer 1

Since we know that a jar of 300g of coffee cost 1.20 £, the only thing we need to do to find how much coffee you will get for 1 £ is divide the amount of coffee you can buy by the amount of money it cost. In other words divide 300 grams of coffee by 1.20£: 
$\frac{300}{1.20} =250$

We can conclude that you can get a jar of 250 grams of coffee for 1£.
