**Instructions**: those are three online calculators that simplify the work to find the percentages. In the first calculator simply enter the percentage and the given amount. In the second calculator you must enter the two numbers you want to find in the report. Clicking on the button "Calculates the result" you know the percentage relationship between the first and the second number. The third calculator determines the percentage increase (or decrease) between the first and the second number.

**Warning:** for decimal numbers is used the dot (

**.** ) and

not the comma (

**,** ) because this version

**does not** take the thousands separators. To help the user, initially the fields have numbers pre-entered. This calculator

**not** provide for the rounding of decimals.
