Money Matters: Decimals in Everyday Life

Decimals and Dollars

Money uses decimals to show amounts less than one dollar (cents). Understanding decimals helps you shop smart and make change.

  • \$1.25 is one dollar and twenty-five cents
  • Adding and subtracting prices to know how much you spend or save

Why Is This Useful?

Decimals help you count money, make purchases, and manage your allowance!

Tips

  • Always line up the decimal points when adding or subtracting money
  • Double-check your change at the store

Examples

  • Adding \$2.50 and \$1.75 to find the total cost.

  • Counting out $0.50, $0.20, and \$0.05 to pay for a snack.
