Gettalie has 4,246 pennies. She wants to trade them in four quarters.How many quarters will Helka receive for her pennies?

Lady bird [3.3K]

Answer:

169 quarters

-------------------

25 pennies

Use this conversion factor to convert 4246 pennies into quarters:

1 quarter

------------------- * 4246 pennies = 169.84

25 pennies

Obviously we cannot get our hands on 0.84 quarters, so round the above result down:

4246 pennies = 169 quarters plus 21 leftover pennies.
