Converting integer or decimal numbers, fractions, proportions and ratios to percentages

It's very simple to write a fraction (a proportion or a ratio) or a decimal number as a percentage.

To convert a fraction:

• - start by dividing the numerator by the denominator
• - then multiply the result by 100%
• By multiplying the result by 100% the value we've got at the previous step is not modified, since 100% = 100/100 = 1
• By multiplying by 100% only the form is being changed - it's written as a percentage.
