What is a percentage? <end_of_turn>
<start_of_turn>model
In mathematics, a percentage (from Latin per centum 'by a hundred') is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign (%), although the abbreviations pct., pct, and sometimes pc are also used.
For example, 45% (read as "forty-five per cent") is equal to: 
- the fraction 45/100
- the ratio 45:55 (or 45:100 when comparing to the total rather than the other portion)
- 0.45 
Percentages are often used to express a proportionate part of a total.<end_of_turn><eos>
