Express 13 mills as a decimal part of $1.00. 2009-03-13
Kenneth pose la question :

I read the following in an old business mathematics textbook: "Express 13 mills as a decimal part of $1.00."

I can determine the answer as follows: There are 1000 mills in or per $1.00. 13 mills divided by 1000 mills/$1.00 equals $0.013, the answer.

My question is as follows: What does "...as a decimal part of $1.00" indicate or represent from "Express 13 mills as a decimal part of $1.00."?

Is (a decimal part of $1.00) any decimal less than $1.00 with the decimal having a dollar sign before it.

I thank you for your reply.

Can you convert numbers with units to percents? 2009-02-12
Kenneth pose la question :
To change a number to a percent, move the decimal two places to the right and add a percent sign. For example, 0.35875 = 35.875%.
If the number has a dollar sign or some other kind of unit, for example, pounds, feet, etc. how is the number converted to a percentage.

For example, change $0.35875 and 0.75 lbs. to a percentage. How is this done. I have never seen $35.875% or 75 lbs.% before.
