Percentages are percentages - simple! The marketing people have not yet come up with "new improved" percentages.
You cannot calculate weights to percentages. Percentages are comparisons of two related quantities so you can have one weight as a percentage of another weight, but not by itself.

The adding machine is actually a calculator. but in the mid 1642's it was called an adding machine. it was used to help with mathimatics
Divide the percentage value by 100.
Of course! Without decimals, you couldn't calculate percentages or fractions. Decimals allow you to break a number up. A decimal is basically a fraction, and when you calculate fraction adding, subtraction, multiplication, and division, sometimes it is easier to calculate a fraction by first changing it to a decimal instead.
An adding machine is a mechanical or electromechanical calculator which could perform addition and subtraction.
