To find the fraction of Mikas' coins that are pennies, you need to determine the total number of coins in the piggy bank. Then, you can divide the number of pennies by the total number of coins to find the fraction.
Let's add up all the coins in Mikas' piggy bank:
12 pennies + 6 nickels + 4 dimes + 8 quarters = 30 coins
Now that we know there are 30 coins in total, we can calculate the fraction of Mikas' coins that are pennies by dividing the number of pennies (12) by the total number of coins (30):
Fraction of pennies = Number of pennies / Total number of coins
= 12 / 30
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 6:
12 / 30 = (12 ÷ 6) / (30 ÷ 6) = 2 / 5
So, the best representation of the fraction of Mikas' coins that are pennies is 2/5.
