Question from Kenneth: Hello: If I want to express 13 mills as a decimal part of $1.00, the answer is $0.013. This amount is found by dividing 13 mills by 1000 mills/$1.00. Can 13 mills be expressed as a decimal part of another amount instead of $1.00? For example, express 13 mills as a decimal part of $1.50 or express 13 mills as a decimal part of $0.10. What would these amounts be? I thank you for your reply. |
Knneth,
Yes, in general by dividing 13 mills by the other sum [also expressed in mills.] Thus 13 mills is 5% of 26 cents, 0.1% of $1.30, etc.
Note however that to express 13 mills as a percentage of $1, 10c, $100, etc. you would normally not use division, but start from the fact that 1 mill is 0.1% of $1, 1% of 10c, etc; then multiply by 13.
Good Hunting!
