There are exactly 20 five-cent coins in one dollar.
To understand this, it's helpful to know the basic value conversion in the U.S. monetary system. One dollar ($1) is equivalent to 100 cents. A five-cent coin, often referred to as a nickel, has a value of 5 cents.
The Calculation
Determining the number of five-cent coins in a dollar is a straightforward division. You simply divide the total value of a dollar (in cents) by the value of a single five-cent coin:
- Total cents in a dollar: 100 cents
- Value of one five-cent coin: 5 cents (or 1 nickel)
The calculation is:
100 cents ÷ 5 cents/coin = 20 coins
Therefore, it takes 20 five-cent coins to make up one dollar.
