Five dollars is worth how many nickels?

The story behind the answer

Five dollars equals 500 cents. A nickel is worth 5 cents, so 500 ÷ 5 = 100 nickels. A quick shortcut: there are 20 nickels in one dollar, so multiply dollars by 20 (5 × 20 = 100).

Fun context: The U.S. five-cent coin wasn’t always a “nickel.” Before 1866, the five-cent piece was the tiny silver “half dime.” After the Civil War, the Mint introduced the larger cupronickel coin (about 75% copper, 25% nickel), and the metal gave the coin its common name. Remember: dollars to cents, divide by coin value, or just use the “×20 per dollar” trick for nickels.
