1.) In mathematics, a percentage 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.
2.) In mathematics, a number base is the number of digits or combination of digits that a system of counting uses to represent numbers. A base can be any whole number greater than 0. The most commonly used number system is the decimal system, commonly known as base 10.
3.) In mathematics, a rate is the ratio between two related quantities in different units. ... In describing the units of a rate, the word "per" is used to separate the units of the two measurements used to calculate the rate (for example a heart rate is expressed "beats per minute").

Answer:
persentage (p =b×r) -the result obtained when a number multiplied by a persent
Base(B=P/R)-The whole in a problem,the amount you are taking a persent of.
Rate(R=P /B)-The ratio of amount to the base,it is written as a persent
