Question

# A mill is a unit of money that is used in assessing taxes. One mill is equal to $\frac{1}{10}$ of a cent or $\frac{1}{1000}$ of a dollar. Money is usually written using decimals. Express each fraction above as a decimal using the correct money symbol. Find the number of cents and the number of dollars equal to 375 mills. Find the number of cents and the number of dollars equal to 775 mills. Find the number of cents and the number of dollars equal to 1,000 mills.

Solution

Verified
1. $\frac{1}{10}=0.1$ so if one mill is equal to $\frac{1}{10}$ of a cent, then written as a decimal it is $\boxed{0.1¢}$. $\frac{1}{1000}=0.001$ so if one mill is equal to $\frac{1}{1000}$ of a dollar, then written as a decimal it is $\boxed{\0.001}$.

2. Since 1 mill = 0.1¢, then 375 mills = 375(0.1¢) = $\boxed{37.5¢}$. Since 1 mill = $0.001, then 375 mills = 375($0.001) = $\boxed{\0.375}$.

3. Since 1 mill = 0.1¢, then 775 mills = 775(0.1¢) = $\boxed{77.5¢}$. Since 1 mill = $0.001, then 775 mills = 775($0.001) = $\boxed{\0.775}$.

4. Since 1 mill = 0.1¢, then 1000 mills = 1000(0.1¢) = $\boxed{100¢}$. Since 1 mill = $0.001, then 1000 mills = 1000($0.001) = $\boxed{\1}$.
