The Straightforward Answer: Twenty Nickels Make a Dollar

The simple answer is 20. Since a nickel is worth $0.05 (five cents), it takes twenty nickels to equal one dollar ($1.00). This is a fundamental concept in understanding US currency and basic arithmetic.

Understanding US Currency: A Brief Overview

Before diving deeper, let's refresh our understanding of US currency. The US dollar is divided into 100 cents. This decimal system makes calculations relatively easy. Common coins include:

• Penny: Worth $0.01 (one cent)
• Nickel: Worth $0.05 (five cents)
• Dime: Worth $0.10 (ten cents)
• Quarter: Worth $0.25 (twenty-five cents)
• Half Dollar: Worth $0.50 (fifty cents)
• Dollar Coin: Worth $1.00 (one dollar)

Understanding the value of each coin is crucial for accurately calculating amounts and solving problems related to US currency.

Calculating the Number of Nickels: A Step-by-Step Approach

To calculate how many nickels make a dollar, we can use simple division. We know that one dollar is equal to 100 cents, and one nickel is equal to 5 cents. Therefore:

100 cents (one dollar) / 5 cents (one nickel) = 20 nickels

This simple equation provides the definitive answer. This method can be easily adapted to calculate the number of other coins needed to make a dollar. For example, to find out how many dimes make a dollar, you would divide 100 by 10.
