A percentage is a way of expressing a number as a fraction of 100 (per cent meaning “per hundred” in Latin). It is often denoted using the percent sign, “%”, or the abbreviation “pct”. For example, 45% (read as “forty-five percent”) is equal to 45/100, or 0.45.

Percentages are used to express how large/small one quantity is, relative to another quantity. The first quantity usually represents a part of, or a change in, the second quantity, which should be greater than zero. For example, an increase of $ 0.15 on a price of $ 2.50 is an increase by a fraction of 0.15/2.50 = 0.06. Expressed as a percentage, this is therefore a 6% increase.

__Remember that:__**100%**of a number is the**SAME**number.**Less than 100%**of a number makes the number**SMALLER**.**More than 100%**of a number makes the number**LARGER**.

**200%**of a number is the

**DOUBLE**of the number and

**300%**of a number is the

**TRIPLE**of the same number.

__Example:__Let's consider the number 50.**100% of 50**is**50****(SAME)****200% of 50**is**100 (DOUBLE)****300% of 50**is**150****(TRIPLE)**

__Example:__225% of 24**200% of 24**is**48 (DOUBLE)**is one fourth of 24, that is to say**25% of 24****24 x 1/4 =**6**225% of 24**is the**sum of****48 and 6**, hence 54
