The ratio of bread to cheese is 2:1, so if you spend \$4.00 on bread, should you spend \$2.00 on cheese? If each loaf costs \$0.10, if you were given \$4.00 worth of bread, how many loaves of bread would you have? \$ a slice of bread = 40 slices of bread \$0.10 NO!

Sandwich Corner 2B C  1 B2C If you have 40 pieces of bread, how many pieces of cheese do you need? Bread and cheese ratio 2 bread: 1 cheese. 40 pieces of bread 1 cheese = 20 pieces of cheese 2 pieces of bread If each piece of cheese is \$0.25, how much did you spend on cheese? 20 cheeses \$0.25 = \$5.00 1 cheese So if you spend \$4.00 on bread should you spend \$5.00 on cheese?

The reason for the Cheese Sandwich problem is that you can’t use the ratio of \$money\$, to use the ratio you have to convert it to the number of elements (molecules) and convert it back. Using the part you are in.
