Lets try and create a simple ratio to find out how much 350g will cost. This unknown value we will call it X.
If 250g of cheese costs£ 3.60.
Then 350g of cheese will cost £x.
Lets cross multiply, 250 times x equal to 350 times 3.60
250x = 350*3.60
250x = 1260
Divide both sides with 250.
250x/250 = 1260/250
x=£5.04
