A hundred dollar bill is $100.00 or 10,000 cents. A quarter is $0.25 or 25 cents. In order to determine the number of quarters that makes up a hundred dollar bill, we need to divide the numbers of cents. That is:
10,000 cents / 25 cents = 400 quarters
You can also work out the problem this way:
10,000 cents * 1 quarters / 25 cents
If you know how to multiply fractions, then you are able to understand how this works. Otherwise, learn how to simplify fractions.
The "cents" are in the numerator and denominator. We can divide them to get:
10,000 cents * 1 quarters / 25 cents
= 10,000 * 1 quarters / 25
One way to work out this computation is to multiply the numbers altogether and divide them. Another way is to reverse the steps of that method and work out the computation. Both of these methods should give you the same number if you simplify the values correctly.
First Method
10,000 / 25 quarters
= 400 quarters
Second Method
Make note that:
10,000 = 10⁴ = (2 * 5)⁴ = 2⁴ * 5⁴
25 = 5²
In terms of these primes or these factors, we have...
2⁴ * 5⁴ / 5²
We can divide the common terms to get...
2⁴ * 5² * 5² / 5²
= 2⁴ * 5²
= 16 * 25
= 400
Therefore, we have 400 quarters.

4 quarters. 100 pennies. 10 dimes. 20 nickels
A quarter is called a quarter because it is a quarter, or 1/4, of a dollar. So three quarters make up 3/4 of a dollar!
A US quarter is worth 25 cents, so 2000 US quarters would be worth 2000 x 25 cents = 50,000 cents. To convert this to dollars, you would divide 50,000 by 100 (since there are 100 cents in a dollar), resulting in $500. Therefore, 2000 US quarters would be worth $500.
