Answer 1

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 %.

Answer 2

=37.83783784

Step-by-step explanation:

Find the total sum of all coins,

which is 37, take the number of pennies and the total of all coins put in parenthesis( 14/37) like so and than * times them by 100

you equation should look like this

(14/37)* 100= and than the answer shown above should be the one you received. I have checked this with multiple calculators, it should be accurate.
