Answer : The percentage of pennies in the collection is 37.84 %.

Explanation :

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


\text{Percentage of pennies}=\frac{\text{Coins of pennies}}{\text{Total number of coins}}* 100

Given:

Number of coins of pennies = 14

Number of coins of dimes = 16

Number of coins of quarters = 7

Now we have to calculate the total number of coins.

Total number of coins = 14 + 16 + 7 = 37

Now we have to calculate the percentage of pennies in the collection.


\text{Percentage of pennies}=(14)/(37)* 100=37.84\%

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