To calculate the difference between these two values, we need to get them to the same measurement. To convert Swiss francs to Euros, we multiply the number of francs (14) by the amount they are worth in euros (0.905).
14 X 0.905 = 12.67 euros
Next, to calculate the difference between the two, we can subtract the 12 euros from the amount of euros the Swiss france are worth:
12.67 - 12 = 0.67 euros.
Therefore, the difference is 0.67 euros
