A 20 Pence coin is a British coin worth one fifth of a British Pound (GBP). A "nickel" is a US 5 cent coin. At current exchange rates (Jan 2011), the British 20 Pence coin is worth about 32 cents USD.
A five pence coin is worth 5 pence, and 7 pennies are worth 7 pence, making the total value 5 + 7 = 12 pence. Since each 2p coin is worth 2 pence, you can determine how many 2p coins equal 12 pence by dividing 12 by 2. Thus, 12 pence divided by 2 pence per coin equals 6. Therefore, 6 two-pence coins have the same value as 1 five pence coin and 7 pennies.
