Let $1 = 100%
Let us start from the smallest and then go to the largest:
Penny: A penny is worth $0.01 (as you need 100 pennies to make a dollar).
Move the decimal point to the right two place values and add a percentage sign:
0.01 = 1%
Nickel: A nickel is worth $0.05 (as you need 20 nickels to make a dollar).
Move the decimal point to the right two place values and add a percentage sign:
0.05 = 5%
Dime: A dime is worth $0.10 (as you need 10 dimes to make a dollar).
Move the decimal point to the right two place values and add a percentage sign:
0.10 = 10%
Quarter: A quarter is worth $0.25 (as you need 4 quarters to make a dollar).
Move the decimal point to the right two place values and add a percentage sign:
0.25 = 25%
Half-Dollar: A half-dollar is worth $0.50 (as you need 2 to make a dollar).
Move the decimal point to the right two place values and add a percentage sign:
0.50 = 50%
Dollar coin: A dollar coin is worth $1.00 (you only need 1 to make a dollar).
1.00 = 100%
10 dollar coin: A 10 dollar coin is worth $10.00
10.00 = 1000%
20 dollar coin: A 20 dollar coin is worth $20.00
20.00 = 2000%
