# Calculating the Percentage of Pennies in a Collection of Coins

## Explanation:

**To calculate the percentage of pennies in the collection, we use the equation:**

**Percentage of pennies = (Coins of pennies / Total number of coins) x 100**

Given:

Number of coins of pennies = 14

Number of coins of dimes = 16

Number of coins of quarters = 7

Now we calculate the total number of coins:

Total number of coins = 14 (pennies) + 16 (dimes) + 7 (quarters) = 37

Now we calculate the percentage of pennies in the collection:

Percentage of pennies = (14 / 37) x 100 = 37.84%

Therefore, the percentage of pennies in the collection is 37.84%.
