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%.
