Number of pennies =3
number of nickels =4
Number of Dimes =5
Total number of coins = sum of all the coins
Total number of coins = Number of Pennies + Number of nickles +Number of Dimes
Total number of Coins = 3+4+5
Total Number of coins =12

Ratio = Number of Nickels : Total number of coins
Ratio = 4 : 12
Answer : A) 4:12
