In US currency, \(\$1\) equals \(100\) cents.
a) Write \(1\) cent, \(5\) cents, and \(40\) cents as decimal parts of \(\$1\).
b) Lucas says, “I have \(\$0.25\) in my pocket.” Give two different ways he could have exactly this amount using pennies, nickels, dimes, and quarters.
Hints
- Think of one dollar as \(100\) equal cents.
- The hundredths place in a dollar amount records cents.
- For part b), make two different coin totals that both equal \(25\) cents.
Solution
1. One cent is one hundredth of a dollar, so it is \(\$0.01\).
2. Five cents is five hundredths of a dollar, so it is \(\$0.05\).
3. Forty cents is forty hundredths of a dollar, so it is \(\$0.40\).
4. \(\$0.25\) is \(25\) cents. One possible coin combination is one quarter.
5. Another possible combination is two dimes and one nickel.
Answer
a) \(\$0.01\), \(\$0.05\), \(\$0.40\)
b) For example, one quarter; or two dimes and one nickel.
