Isabella has some nickels in her purse. She wants to swap them with her mother for a quarter and a dime. How many nickels does she need to give?

Isabella has some nickels. She wants a quarter and a dime. We need to know how many nickels will equal the same value as one quarter and one dime. Here, we have a quarter and a dime. We need to ask the question; how much is one quarter and one dime worth? One quarter is worth 25 cents. And one dime is worth 10 cents. We can add 25 cents plus 10 cents. That equals 35 cents.

To solve this question, we need to know how many nickels would we need to equal 35 cents. Every nickel is worth five cents. If we had two nickels, we would have 10 cents. Let’s count by fives to see if we have enough nickels now. Five, 10, 15, 20, 25, 30. So far, we have 30 cents. Six nickels equals 30 cents. That’s still not enough.

If we add a seventh nickel, we would say 30 cents plus five equals 35 cents. It takes seven nickels to equal the same amount as one quarter and one dime. It takes seven nickels to equal the same value as one quarter and one dime. If Isabella wants to swap her mother for one quarter and one dime, she will need seven nickels.
