How many dimes equals the same amount of 1000000000 pennies?
1,000,000,000 pennies / 10 = 100,000,000 dimes. This is true because 10 pennies equal one dime.
How many dimes equal the same total amount as one billion pennies?
Since each dime = 10 pennies, the number of dimes with the same value as a group of pennies is 1/10th the number of pennies.1/10th billion = 100,000 dimes have the same face value as 1 billion pennies
How many nickels are equal in value to 20 quarters?
A nickel is 5 cents and a quarter is 25 cents so there are five times as many nickels as quarters in any amount. That means 20 quarters is the same as 20*5 = 100 nickels.
How many dimes are in 50 nickels?
There are no dimes in nickels. But 25 dimes have the same monetary value as 50 nickels have.
How many different coin combinations could a person have if she has exactly 21 cents?
Assuming only the use of currently produced US coins, there are 9 combinations: 21 pennies 16 pennies, 1 nickel 11 pennies, 2 nickels 11 pennies, 1 dime 6 pennies, 3 nickels 6 pennies, 1 nickel, 1 dime 1 penny, 4 nickels 1 penny, 2 nickels, 1 dime 1 penny, 2 dimes If you allowed the use of obsolete denominations (half cents, 2 cent pieces and 3 cent pieces) the number would be higher, and if you further differentiated between different coins of the same denomination (e.g., large cents vs small cents, three cent silver vs 3 cent nickels, half dimes vs nickels, etc.) the number would be higher still.
