Percentage of Pennies in a Collection of Coins

To calculate the percentage of pennies in the collection of coins, we need to first determine the total number of coins in the collection. In this case, the collection contains 15 pennies, 14 dimes, and 6 quarters, which adds up to a total of 35 coins.

Now, to find the percentage of pennies, we divide the number of pennies by the total number of coins and then multiply the result by 100 to get the percentage:

Calculation:

Total number of pennies = 15

Total number of coins = 35

Percentage of pennies = (15 / 35) x 100

Percentage of pennies = 42.9%

Therefore, the percentage of pennies in the collection is 42.9%. This means that approximately 42.9% of the coins in the collection are pennies.
